Will your false copyright claim cause someone to lose money? Well, you'll have to pay them back if they prove the claim is false, so better triple check the content for fase positives, fair use, etc., before claiming anything.
There is some merit in limiting who-can-file-for-what, however it also annoys me since it also closes off a route of activism which could help force a consistent application of the rules. (Thus exposing both how bad the system is and also forcing rights-holders to curb their overreach.)
For example, imagine that AcmeCorp lawyers were to abuse takedowns to remove negative reviews of their product, while ignoring positive reviews that are equally-or-more "infringing." Or if multiple companies arranged a kind of ceasefire-cartel while using the law to persecute others. If a citizen could "help" them with removing all that content they "missed"...
Insufficient
But the prerequisite to the above argument is that people have a right to upload to YouTube; we don't, but it would certainly be a better service if its users weren't plagued by false copyright claims.
I'm sympathetic. I think I even agree. Policy will be tough to craft here, sadly.
Or, something to that effect?
