I've especially not enjoyed Windows occasionally hijacking the post-login screen to try to convince me to enable Cortana or whatever. The most frustrating thing is the only options when presented with the window were "Continue" or "Remind in 3 Days", rather than "Fuck Off". This abuse of user agency & consent is disgusting and ubiquitous in big tech.
Video games are the only thing keeping me on windows, plus last time I tried to set up a dual-boot with Ubuntu I somehow trashed the boot process of both OSs.
