If anyone still wonders if they should buy #OnePlus: No. You should not.
They've now put a hardware-based anti-rollback feature in place that, if you try to roll back (f.e. to install a custom ROM without Google spyware or because of some other issue) your device will be hard bricked, irreparably.
They're worsening for years now, this is just the newest addition of crap they pull.
