By reading about the new inclementations on Google I decided to leave from Google services entirely, already stoping using Windows for 6 month and Chrome, but sttil dont sure about a gmail(Some important things are signed in gmail accont) and some services like Youtube and some android telemetry(already rooted)
Totally agree with this. I started with Gmail and calendar and then gradually continued with Gdrive and Gphotos. My browser has always been Firefox, so no problem there. My next step is owning a Google-free phone (keeping an eye on https://tuxphones.com/). The only thing that I can not get rid of is Google Maps. It works so damn good!
