I think that decision makes sense.

What you said got me worried, so I looked into the claim that it is “tracking all your behavior for advertising purposes and whatever else Apple decides”. That’s a convincing concern, and you’ve changed my mind on this. I don’t see any evidence that they’re doing anything close to this level of tracking — the main thing they seem to track is your Mac App Store usage — but they may have the potential to do so in the enshittified future. That gives me pause.
