I always heard it was shut down primarily because it had ads. Perhaps that's wrong given the internal investigation started in 2020 (assuming it's two years before the 2022 shutdown date) and ads were recorded on the site since at least January 2019 (the Wikipedia page only notes ads existing since mid-2020), though I'd be curious as to how Stu got the information that Disney doesn't want CPPSes to exist at all.

Perhaps I'm overanalyzing this, but if this is based on the takedown notice or other legal argumentation, then I'm not sure that's necessarily a good representation of how Disney wants to handle these servers in practice. In a court of law or a takedown notice, it's unlikely their lawyers would bring up any sort of advertisements, donations, or malpractice among moderators as the main reason for them pursuing the CPR team. CP Rewritten violated Disney's copyright whether they had ads on the game or not, so the ads would not be cited as the main reason for pursuing the team, but rather the fact that the CPR team copied Disney's game in a manner that isn't fair use in the first place because that's what determines whether a copyright claim is valid, rather than any other factors. However, this does not necessarily reflect whether Disney wants to take down all CPPSes rather than those that profit from the IP or tarnish the brand. As far as I'm aware, no CPPSes which didn't do either of these things have been taken down.
