If you've ever tried using the Xbox Game Pass for PC, I think them offering it in itself will move users away to other stores and platforms. Not only are download speeds abysmal, but it frequently takes forever to even start a small update. Oh, and no option in the GUI to backup your games. You can only change your home computer 3 times. Reinstall your computer a few times and you will no longer be able to use offline play for a full year and you'll have to wait days to reinstall your games.
I am a subscriber and I will admit I hate so many things about the app, I genuinely don't know how a company the size of MS can make the UX mistakes it does.
Anecdotally though, I haven't seen the issue you mentioned with the download speeds. It always maxes my 150Mbit connection (probably pitiful for some parts of the world admittedly) so I've never felt a need to backup games because I can re-download them whenever. I'd be interested in hearing about this 'changing home computer' limit too, I've got my game pass running on 3 computers right now so I'm curious if I've hit the limit.
As I mentioned in another post, I am a daily linux user and want to see it become a wonderful gaming platform. That said, even with the UX issues of game pass, it's hard to argue on the price point. For a none techy who doesn't care about OS choice or brand loyality, I think it's going to win in the long run.
