I've decided to call those locked-up, locked-down straightjacket operating systems "kiosk OSes" because they are designed to be used like a kiosk, only in the way the vendor intended, with no user-serviceable parts. You are not the owner; you are the user. The vendor is the owner. That, in a nutshell, is why I will only ever own an unlocked Linux phone. I'm a creative. I'm a hacker. I want to own my phone.
