This is kinda FUD, right? Google-Android has a lot of privacy invasion. But there are all kinds of Android versions that are de-Googled.
Well, for one that quote does also say "as well as the apps and services recommended by them". Most Android apps come with ads and tracking built-in, because Google makes it very easy to set that up in the standard Android development toolkit. Similarily, lots of Android apps require the Google Play Services.
But the open-source part of Android (AOSP) still has design decisions which work in favor of advertising. There's no internet permission for apps, for example, even though this could resolve many security concerns.
Which kind of brings me to more of a personal opinion: Android is also just bad.
Its filesystem is pretty much completely broken, because Google would prefer you put your data into their services rather than keep it offline.
Hardly anything can be scripted.
Getting admin permissions on your own device is an ordeal.
In many ways, I like the Plasma Mobile UI already better than the Android UI.
And going back to my first point: The whole ecosystem is hostile.
In particular, I also like to tinker with and improve the ecosystems that I use. I do still use LineageOS, and I just set it up so it's acceptable to use, then I leave it alone, because I'd rather invest my time into ecosystems that I actually like.
