Being a devil's advocate, you COULD call their firmware bs a MASSIVE fuck up and not necessarily malicious, and while painful, probably survivable even with a lawsuit....IF...
IF!!!... They took accountability. Joking about it is ABSOLUTELY pr suicide, you'd probably be better off company wise shooting the person who joked about it in the head during a live stream.
This is probably the most mask off shit I've ever seen, that they brick hardware and essentially lol about it.
That alone will definitely boost class action lawsuits as an "oh my God we fucked up we are so fucking sorry" wouldn't prevent it, but would lessen a lawsuits scope.
