Fdroid, free and open source alternative to the play store. I've been using it for months, and while it's barebones and probably too minimal for most people, I rather like it myself.

I bought a Pixel 8 Pro and installed GrapheneOS. No account signed in to the OS or Google play. You can run it completely Google free or run Google services in a sandbox mode with normal controllable permissions (alot of stuff uses Google services for push notifications and some other stuff.)

Use FOSS (Free Open Source Software) where possible, you can get a cheap domain name and cheap email hosting to move away from gmail.

You could go a step further, pick up a raspberry pi, and start self hosting some things to move away from Google apps.

It's all pretty relatively simple these days, but you have to be open to learning at least a little bit (mostly the last part, gOS is basically one click install and some email hosts are about the same - but still.)

TLDR: Moving away from services you pay for with your data will require paying with your money or time, but it's worth it.

It’s the same as Steam, you sign the contract called “ User Agreement” that has a section on how you don’t own the games. It’s legal and nothing you can do about it. User Agreement also forbids you from suing Valve Corporation, so anyone who wants to own games from SteM legally cannot.
