When @wired.com made FOIA-based stories free, subscriptions went up. When @404media.co published public records reporting without a paywall, new sources came forward. We spoke to both about why dropping paywalls like this is good for journalism — and for business.

This thread does a better job of capturing why the cloud isn’t merely “renting a bunch of servers” than anything else I’ve seen recently.

Informative thread.

Good thread from @signal.org CEO, @meredithmeredith.bsky.social underscoring our critical dependencies on a few key orgs, and an increasing challenge in organizational and national resilience. We have a lot of work to do. cc @gate15.bsky.social

Excellent thread that I kinda had been waiting for. 👇

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms). It’s also concerning. 1/

Pray, Mr. Altman, if you put into the machine correct figures, will the right answers come out?

Your favorite thing is down because DynamoDB at Amazon's AWS US-EAST-1 Regionwoke up with Main Character Syndrome. This is the default /legacy backbone for a ton of things. Including Amazon's own stuff. Massive outages. Here's what's going on & what we know 1/

PSA: we're aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.

"I don't have anything to hide why should I care about privacy?"

LOL all morning picturing some finance quant slouched at his desk prompting Dalle, like, "make me a picture of pikachu having sex with the Apple logo" or whatever tf those guys use these things for, then throwing up his hands like "WHY WON'T THIS FIND ALPHA?!" www.bloomberg.com/news/article...

I wish more people knew that there’s virtually no way to prove media or text is AI-generated unless you created it yourself. “AI detectors” aren’t proof. Among other glaring issues, this makes it more difficult for journalists to report on media being AI-generated even when it seems obvious

For those who want to know about how I chop vegetables between meetings, or grind my coffee, have I got the article for you www.businessinsider.com/day-in-the-l...

これ面白かった。秘匿性が高い通信アプリの筆頭格であるsignalのMeredith Whittaker（元Googleの研究者）のインタビュー。 GoogleやMicrosoft、Apple等々のテック企業は基本的にユーザーの個人情報や利用情報などのプライバシーを餌として利用することを通して利益を上げていることや、その最たる例として昨今のAI技術が使われていることを解説している。私たちがネット上で日々交わしているあらゆるメッセージは、常に誰かに利用されるリスクに晒されており、それに対して人権としてのプライバシーが主張される。 youtube.com/watch?v=8BUU...

We love to see it <3

We're so relieved to see Germany reaffirm its opposition to the dangerous Chat Control proposal--the one that would mandate mass scanning of communications. Germany's long been a solid champion of privacy, and the news that it was considering backing mass surveillance was alarming. 1/

FWIW I've written to the Irish Minister for Justice - an enthusiastic supporter of Europe's hideous "chat control" phone-scanning proposal - asking him to imagine when that technology is used against him. If you're German, please, PLEASE write to your justice/interior minister today.

I think you completely misunderstand what this bill represents. Read up on it www.patrick-breyer.de/en/posts/cha...

Take action! fightchatcontrol.eu to contact your ministers, permanent representation, MEPs, and, if you are German or Italian, your national MPs!

Here's a video explaining how Chat Control surveillance would work by the Max Planck Institute for Security and Privacy... fair.tube/w/72DCPMByyS... #speirgorm

No, my message is that govs are containers for power, which can be exercised brutally or w wisdom, & tech is a collection of methods that can be abused or leveraged for good. TLDR tech and gov aren't stable categories. Validate both (like, by examining Signal's open source code) before you trust.

This is an EU proposed policy with the benign-sounding name "Child Sexual Abuse Regulation" which proposes to screen private online communications using sketchy image-scanning algorithms. It is technically unworkable, and would be a privacy catastrophe, especially for those in authoritarian states

OK, by this logic...the surveillance of every facet of life--from comms to movement to social relationships to etc--which has become the norm over the last decades c/o the surveillance biz model, makes LE surveillance MORE possible than it's ever been in history. But somehow e2ee is the problem?

📣 Germany's close to reversing its opposition to mass surveillance & private message scanning, & backing the Chat Control bill. This could end private comms-& Signal-in the EU. Time's short and they're counting on obscurity: please let German politicians know how horrifying their reversal would be.

NEW: breach of Discord age verification data. Including some users passports & DLs Age verification is a badly implemented data grab wrapped in a moral panic. Mark my words, as age verification mandates expand, we'll end up more surveilled and less secure. 1/

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

Over the years, Michelle Visage on RuPaul’s Drag Race has dropped some iconic looks, but 1980s Long Island @meredithmeredith.bsky.social is going in the pantheon.

“We are not working on building an AI agent. We are working to protect Signal from the invasion of AI agents that threaten privacy and that are being implemented in irresponsible ways”

the discussion of AI agents as systematic points of sensitive information leakage is particularly good.

I loved talking to Signal's @meredithmeredith.bsky.social, who is such a consistent, clear voice of sanity (and always a great interview). We talked about (of course) SignalGate, what AI means for Signal, why tech bros continue to be such a disappointment, and much more. Read, listen, etc!

Any excuse to hang out with @katie-drummond.bsky.social I'll take. This was so much fun!

New speakers. I'm officially a dad.

“It will not be possible for apps like Signal to provide strong privacy guarantees (…) if device-makers and OS developers insist on puncturing the metaphoric blood-brain barrier between apps and the OS” #tech #Ia

AI agents promise to “put our brain in a jar while a bundle of AI systems does our living for us”, writes Meredith Whittaker. “But as in fairy tales, so in life: relying on magical fixes leads to trouble,” she warns

It's Signal. It's worth using. Good interview with @Mer__edith https://english.elpais.com/technology/2025-09-14/signal-president-meredith-whittaker-in-technology-its-way-too-easy-for-marketing-to-replace-substance-thats-whats-happened-with-telegram.html h/t #signal

“A fundamental shift is needed in how we approach the development and deployment of AI agents,” argues Meredith Whittaker. “Basic lessons in privacy and digital security are being discarded,” she warns

“AI agents can be coaxed into revealing sensitive data they have access to or tricked by hackers into taking harmful actions—from extracting sensitive code to creating havoc in homes by activating smart appliances.” Happily, it’s not too late says @meredithmeredith.bsky.social @economist.com 🧪
