I have found Surveiliance Report quite a while ago actually - I think I am watching them for one and a half, maybe even more, years now? Basically, I got sick and tired of all this data collection and started to look into alternatives - and naturally, ended up there!
With all the things I learned there and software I found with the pointers given throughout the shownotes, I now run LineageOS 20, MicroG, Magisk, AdAway and a few other things. No more Google. And prior to that, I sold my iPhone and Apple watch and completely detached myself from the Apple ecosystem. That was a full 180° because I had been an Apple user since... 2008? XD I'd have to check, but I owned an iPod Nano 5th gen when I did my first iTunes purchase with Click&Buy. I was there very, very long. So giving up on that ecosystem was quite a cut.
