How can they make this apply retroactively though? For already shipped titles, if I'm no longer providing updates anymore, how can they force me to pay money?
I'm aware that games no longer have a final shipping date, with early access and all, and as a dev I'd likely would want to offer continued support in such a scenario.
But the way I understand it from the overall public reaction, is that they're trying to charge customers for existing titles, retroactively, in perpetuity going onward. This would be a one sided ToS change which only benefits them, which they push the customer into agreeing. Such a practice is mostly unenforceable in a lot of jurisdictions around the world.
