Will once again re-up the concept of a “right to root access”, to prevent big corps from pulling this bs over and over again: https://medhir.com/blog/right-to-root-access
If a company offers some benefit at the cost of some restriction, then users should decide if that benefit is worth the cost. For most Android users, it will be - my grandma isn't interested in the freedom of indie devs to develop for her phone, she's interested in not accidentally installing malware.
I don't like that as much as you don't - for my own devices. But like anyone else who cares about that, I can root it and get past the digital nanny state.
Owner having full control over the device does not prevent a company to offer same benefits and restrictions. But these restrictions need to be optional, so the owner can decide whether to enable or disable them.
