This is a silly take. Game Pass is the best value in gaming today by a huge margin and I say that as a general naysayer of MIcrosoft. It is a reasonable take for someone to stay with MS because of the service.
Theres no reason to be childish. There's lots of alternatives to game pass that will net you significantly high quality experiences without supporting convicted monopolist Microsofts Disney-ification of the games industry.
This take is ignoring the social nature of much of gaming. Changing which set of games I play is one thing, convincing my friend group to go with me is another. Especially for my friends whose primary way of playing games is on an XBox, meaning we rely on cross play as much as we can
You can just not have what's on Game Pass. You will survive. It didn't exist a couple years ago, but now you can't do without?
