Apple just lost the ball on privacy. Apple is supposedly delaying the CSAM scanner, probably until after the holiday season so as not to hurt sales. That Apple didn't kill it outright is a worrying sign. The CSAM scanner is a massive violation of user privacy that undermines anything else Apple has claimed or done for user privacy.
Apple killed the notion of privacy across its entire ecosystem.
So that leaves you with reliability on your list of reasons to stay and how important it is for you.
Personally, if I were a fresh Apple user who wasn't tied to the platform and moved over because of privacy, I would immediately leave unless Apple completely disowned this mess, and the people who are responsible for it within Apple depart Apple.
As it is, I'm very much in the Apple ecosystem so I'm not digging deeper until the scanner effort is finally ended. No more iPhones, iPads, Apple Watches, Apple TVs, Macs or software updates for me. I'll be fine for several years like that. When the time comes to upgrade, I'll find an alternative.
