No, the bans stem from the EULA. I am not breaching the EULA. Whether Plex can verify that or not is not much of a concern for me.
But to be clear, I have zero to lose here. The outcome of Plex banning me for not breaking their EULA (for some reason, which is technically possible but unlikely) is the exact same as the outcome of me dropping Plex in case they ban me. In both cases the only thing that happens is I'm not using Plex anymore.
Also, in your hypothetical Plex already knows the stuff you are worried about. The SSO has nothing to do with it. Plex doesn't need data from Google to know, they already have your personal information.
I guess adding to the list of reasons to use Plex "being berated by online randos wanting to be performatively tech savvy". Which, again, changes nothing practical, but hey.
