This is pretty well trod legally. By the user taking a specific action, it makes the user responsible. Comma.ai uses the same technique. Technically their self driving hardware comes with no software. You have to click a button and point it at their GitHub to get the software on it, but it's automatic after that.

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!

I forget, doesn't Audacity also have you do this, if you want to be able to export projects as MP3?

yes, although the I recently tried doing this on a cloud Ubuntu instance, and it refused to see the .so file

winamp did something similar, you actually had to whip the llamas ass yourself
