They have said that the bootloader will be unlockable. I doubt they'll do much more than that but if it's unlockable then the Community will hopefully get LineageOS or other ROMs working.

They already replied. Said unlocked but will void your warranty yadda yadda.

But:

The hardware drivers (especially for the built-in keyboard) may be proprietary.

So that's a show stopper unless they provide a binary.
