They don't have a history of cancelling pre-orders. They have a history of cancelling pre-order, singular.
I get your overall point, I just think you're going too far with it and being rather disingenuous when you warn people that their reservations will be cancelled if they complain.
I do. They have previously done exactly that. That's my only point, Tesla has a history of attacking critics including cancelling pre-orders.
My only "axe to grind" is for Tesla to stop attacking critics and to instead go after their argument. If Tesla disagrees with a negative review/experience, that's fine, but don't try to punish people for raising issues.
