I think it is more along the lines of people being afraid that their users might break copyright law. For instance: my website allows users to upload profile pictures. From the sound of this, if one of them were to upload a copyrighted picture, _I_ am liable. My website is small right now, so monitoring this is feasible...if it gets much larger, I would need to hire a team of people just to police it. Obviously, if somebody says "Hey, Ryan, user $foo has uloaded picture $bar, would you mind taking it down?" I will, but if this is the way boingboing is making it sound...it won't be that easy.
