But...as we've (in the all-inclusive sense...not being condescending towards you, Matt) reiterated in the past, the videos aren't really "theirs" to begin with anyway. Unless they actually do hold the copyrights--and I'm guessing they probably don't--they don't really have a leg to stand upon, right?
No, of course they don't, but that's not the point. The trading circle, near as I can tell, is fairly incestuous, and I would imagine if word gets out that someone's not honoring the conditions of the trades they are making, that someone probably should hope that they are happy with the size of their library, because they're gonna get blackballed in a hurry by anyone of any note and they're not going to get so much as a sniff at anything exclusive or valuable ever again.
Now let's turn that around: let's say I happen to be the holder of something rare, and I trade it to someone, and that someone turns right around and uploads it to YouTube despite my request not to. And maybe that pinhead gets blackballed. Fine.
Then, a few months down the road, I get burned by another, different pinhead.
Do you think I'm likely to stick around and get burned a third time?
