It’s only a problem because people in general are not willing to pay for it.
You and the OP have the same problem you want a solution but are not willing to pay the price. And you think that what you want is what most people want, but from what the market tells us they are pretty happy with what is being offered right now.
So let's say I'm willing to pay double or triple rate or more if needed, then show me a flagship phone with the same capabilities as a normal Android flagship phone but without the loss of privacy and ownership. You can't and you never have been able to. No completely free phone on par with flagships have ever been released.
