I think a recent court decision in CA determined that unless the website is a front for a brick & mortar real world place, they're not subject to the CA version of those laws (Unruh). How that would play with the ADA rules, I don't know, but this article mentions both. I'm not sure this issue is at all settled nationwide, but my take is bringing that lawsuit in CA won't get you very far.
Kind of a shame, because it was my first thought too--losing the accessibility team and then removing all the accessible clients definitely won't make Musk many friends among disability advocates.
I do wonder, as a late afterthought, though, whether the legal principle behind making your accessibility worse via negligence or deprioritization (the internal team) or lack of due diligence (these apps) could be different than whether the government could require you to include it in the first place.
