There are a lot of different types of Android projects. I think we have to differ between AOSP (Android Open Source Project) Android One, Google Services and so on.
And there are community driven Android projects available - with as less Google as possible!
You can even buy a FP3 and a FP3+ with a preinstalled /e/ OS (which is based on LineageOS)!
And LineageOS for FP3 should get official very soon, too!
Indeed, it needs some steps to install a different OS like LOS on your device. But you don’t have to be an IT specialist.
