Yeah, I am sure it is! What is even more annoying is that I didn’t even receive an email from Microsoft that it was happening (not sure if that was just me). I am sure it is illegal (or at least a breach) but I can’t imagine how many likely costly hoops you would have to jump through to get them to honour the agreement.
Maybe I am just an old nostalgic fart but I have games that I own that are over 30 years old that I still have access to and regularly play and that’s how I like it.
I personally don’t at all see any benefit to the consumer that subscription based gaming provides. Arguably you can access more games for less money, but if video streaming is anything to go by (increased prices, less content across more and more services, ads creeping back in etc), that value proposition won’t last long.
