I cannot relate to most of your points. I’ve never seen the ads you describe. UI made a huge leap forward after they neglected it for decades, so it almost caught up to the usual Linux DEs (as they were some years ago). System performance is not worse than on my several Linux systems.
I just don’t see the point in switching to Linux now, if you haven’t already done years ago.
Probably. But maybe it is my habit of unshitifying every OS I install. I always decline telemetry, ads and suspecious features since Win10 rolled out. Same on my android phones. Use adblock since I cannot stand seeing ad banners without freaking out.
My point is: Microsoft and Google always offer opting-out. Users are responsible for accepting or declining services like telemetry. If you still cry about this crap: FIX YOUR CONFIG.
