Looking it up it really seems "OVA vs. OAV" mainly came down to two publishers, Kadokawa & Gakken, having a spat over semantics.
Gakken insisted on "OAV" while Kadokawa insisted on "OVA", & apparently some argued that "OAV" associated it with porn, which is known as "AV" in Japan, so "OVA" won out.
add a skeleton here at some point
