I somehow can’t imagine them doing this for fun.
The Fairphone 2 didn’t have a lockable bootloader to begin with, and if I remember correctly the Fairphone 3 didn’t require such a code to unlock the bootloader initially, this was introduced with an update somewhen later.
Google certification for Fairphone OS perhaps?
@anon32471517: Why is it required to generate a bootloader unlocking code?
If temporarily … certainly very annoying.
Else (depending on why the code thing is done we probably shouldn’t look forward to an “else” case) they perhaps could supply a script for self use or self hosting (thinking of something like this from the past - Edit: doesn’t work anymore, I might add).
