> Or in the case of my OnePlus, their updates added so much of their own shit to a once pure OS

Same situation on preinstalled laptops and Android. You are complaining about Google in relation to Microsoft.

Android One was a correction to how their system should work and it wouldn't help their goals to sell $100 phones that are secure, all an older adult would typically want, not particularly engaging for marketers, competing with their flagship phones for people who will pay and accept any quality in pointless toys.

Even their own A series has been a problem for them since it covers what any reasonable person would want (in a flagship eliminating way). So let's restrict the charging bellow the lowest industry standards, etc.
