There's also this company called "Apple" you might want to look into, if privacy is relevant to you. ;)
No root. I prefer owning things to leasing them.
You have to trust them, though.
They sayy they care about privacy and yes, they make most money on selling devices and not on advertisement, but who guarantees that is not to change any moment?
And aren't they allready in the advertisement buisness as well? So also have a motive for getting and evaluating all your data?
Google - Wants my data, willing to play the long game, has the scale to properly support security updates
Third party US manufacturers - Wants my data, playing the short game, suspect UI choices
Chinese manufacturers - Wants my data, suspect UI choices, unknown motives with regard to data privacy
Open source OSs - High data privacy, absolutely controllable OS
Weighting between the 4, my threat model prefers a Google phone, despite the privacy downside. Google does creepy things, but ultimately they don't really care if a power user turns off tracking: they only care if everyone turns off tracking.
