It isn’t your computer, user license clearly states you’re renting the software. You always have been, it’s just now they can enforce that agreement more readily. Microsoft is making a lot of bad decisions at the moment, but the majority of consumers really don’t care - adverts and surveillance are what they grew up with.

You can switch to Linux, but as much as I love it (it’s my daily driver for work and for travel gaming, oh and the community is absolutely amazing), it’s not 1-1. You will have to jump through hoops sometimes to get things to run (but damn me there are amazing people out there who can and do help). Then again, you own it because it is free, and it will run most things with the right tweaks.

I can’t speak for MACs (too poor to use one, my devices tend to be upgradable or VERY long life), but I hear they’re a better experience in terms of less bloat/adverts. Again though, you are renting with Apple, and are largely trapped in their ecosystem, and they have a ‘reputation’ for lack of repairability…
