> I strongly disagree with this. I see no way to rationalize that a company should be responsible for ensuring that counterfeit devices work correctly by releasing drivers that are tolerant of them or do not stop them from functioning.

There's a difference between not taking steps to ensure counterfeit devices function, and purposefully causing hardware to fail on a remote system. For example, I'm pretty sure purposefully causing the problem is illegal, if the user didn't request it, as it seems the same as hacking to me.

Refusing to function is acceptable. Bricking the hardware is not.
