Years ago I tried uploading my daughter's recital to youtube as a unlisted/private video to share with out of state relatives.
Thanks to the music, it got an instant copyright strike. That was the last time I uploaded to youtube :-/
And that would presumably be evidence of however many doofuses trying to upload their entire music library to YouTube privately.
It both doesn't make sense - you're making a private collection - and also does; YouTube have a for-profit music streaming service.
I guess we're now entering an era where we don't just have to worry about *just* paperclip maximization, but also the dimension of "how many paperclips the humans are leaving in the training data when they walk away from the LLM" :/ - in this case, if you upload 1000 songs into a private playlist then fine, maybe penalize that. But for a single video? That's messed up.
