To some degree, the closest we have to these situations besides getting flagged with TOS violations (whether real or false-flagged) in these companies are residents of countries that are either trade or economically sanctioned by the USA.
Thankfully we haven't seen something like an account ban and deletion incident for such cases, but the severe ones I can remember usually prohibit access entirely and that'd be scary if it extended to primary services that others rely on for auth.
You will be effectively locked out to services if it's all that's linked and that identity provider just decided you'd be persona non grata.
