This is absolutely unacceptable. That's like you having to submit your personal details to Microsoft in order to just run a program on Windows. Absolutely nuts and it will not go as they think it will.
How will it go? Where are people going to go? People who draw a hard line on this can’t go to iOS for more freedom. Linux phones aren’t ready for prime time. So what’s left? Going back to a flip phone that doesn’t even have the capability of running apps in the same class?
we need more OEM unlockable phones, though. GOS is looking at getting one made, I'm planning to throw money at them to make it happen.
It's the implementation that OEMs used to support VoLTE isn't compatible with AOSP APIs.
If it wasn't for Google here you'd never have VoLTE on custom ROMs, if it exists in any shape or form it's thanks to them.
