Anecdotal, but I doubt there is much hard evidence about reasons people stop using Google products, or even if individuals do, or whether there is just less growth.

I have decided not to buy a Google phone next time, and to start the mamoth task of moving my primary email address to one using a domain I own rather than a gmail.com one (changing email address is hard :( ).

It isn;t so much because Google is evil, it is because their stuff isn't as good as it used to be, and they arbitarily lock people out of accounts for poor reasons, or force changes on people, at times. I have a Pixel 4 and have been pretty unimpressed with it as a phone and with how buggy Android seems to have become. I've also, over the past few years, started to dislike their stuff more and more. Having to use G Suite for work, as a user and an admin of it and supporting users (though I don't actually suport them directly myself), puts me off their stuff too.

Google no longer makes good products, but they think they do, and change thewir stuff on the assumption that they are improving it when they are not.
