He certainly doesn't think it is a mistake. And that would fall within the spectrum of possibilities, but I would doubt anyone considers that as a probable reason, since it would be stupid to push something like that right now. Like future-destroying stupid.

So instead they try to push the garbage down to us. And they are doing it entirely wrong, even from a technical standpoint. I'm sure there is some lawyer there who says "we'll have to go through motions to protect against a lawsuit". But legal reasons do not make for good technology, or good patches that I should apply.
