For everyone who bothered to get worked up in this thread, 4 days ago Trump signed an executive order that mandated payment processors revoke these rules. The games are coming back. Steam and other sites are no longer bound by Visa/Mastercard by executive branch mandate within 180 days. If these games don't return, it's because Steam or GOG or Itch refused to bring them back.
If you're having a hard time coping with that, what you want to look up is
>GUARANTEEING FAIR BANKING FOR ALL AMERICANS
or more specifically
>Sec. 4. Removing Reputation Risk and Politicized or Unlawful Debanking.
It's already active, so the payment processor game bans are over.
