For the love of god users have to read the terms , the GCU, digitally you owned a long term license to play with your games but you did not owned them at all, If Microsoft, Sony, Valve etc want to remove them from their library and from your library, they can do it. I saw only GOG who did the digital games right.
Maybe if that guy played it online by spreading his story on X etc, M$ will do something but they are not obliged to do it, we need a law that constrain they big companies to do it like GOG for exemple or an alternative way.
