I recently bought a phone from Volla that ships with ubuntu touch. Somewhat painful, but entirely possible to use. I also backed the liberux indiegogo for a more modern proper mainline linux phone again.
I'm just not using any google play and ios exclusive apps and services anymore. Yea it's painful but if you want to see an ecosystem outside of google play and ios, you have to buy and use it. Just be prepared to be the 0.1% that literally nobody cares about. Like when traveling I can follow my ICE train schedule on the Deutsche Bahn website, but it will log me out and delete my entire state after 15 minutes or so of inactivity. Or a couple of years ago I saw that uber had a web app and at some point wanted to order one for a group. turns out when trying to finish the order (which you can't dry run), I got a generic error and someone with the app had to order. After uber sent me 125 marketing mails after that, telling me to order discounted food with uber eats, I think I finally unsubscribed (I only didn't earlier out of morbid curiosity).
Personally I live by just not using this stuff is better than being like "oh I need waydroid to run android in a container and use the reverse engineered reimplementation of google play, and also need to fake some stuff to pass integrity checks etc. to use an E-Scooter".
