We lost a Supreme Court case in 2005 on "inducement liability" (not a familiar copyright doctrine before that).

I'm not sure if this doctrine has continued to be applied to anything else.

That's a good point. The other examples didn't involve copyright.

Hopefully since it's so old, the copyright holders are cool about it.

ps. Hi Seth, good to see you around!
