The record companies are always trying to make it someone else's responsibility to police their own property, but this is ridiculous because no one else *can* properly monitor for infringement.
This is because copyright infringement relies on a lack of permission. If someone has permission from the copyright holder to upload something, it's not infringement!
They have repeatedly shown they don't even have a grasp of this. For example, multiple cases where videos or music content has been obtained from YouTube videos, which is then incorporated into another broadcast program, which is followed by a DMCA takedown to YouTube to remove the original videos that were the source of the clip or music, which are items the broadcaster does not own.
There have been cases of musicians doing original songs which they post for sharing or enjoyment, and the music is noticed and used in a production either under creative commons, or under an actual license to use the music, or sometimes no license. Then they come back to YT and demand a takedown on content they didn't create and don't own and have no right to suppress. Except their copyright filter says they did and demands it.
One recent case was where old video game footage found on YT was picked up -and I recall this was without permission- by the Family Guy show and used in an episode. Fox then went back to YT and demanded DMCA takedown on the ORIGINAL video they stole to use on the Family Guy episode. Because, you know, the clip they stole does match a few seconds of a particular episode, because it was the same footage, because they took it and used it. The creator of that game video was threatened with having his Google account suspended for copyright infringement on material he himself had created and recorded. As I recall, the DMCA was reversed and then reimposed again, followed by more appeals and public outcry.
From time to time, I work with a music company who sells royalty-free music. You pay once for a non-exclusive license and you can use it in that production forever. The customers buy a license but NOT the copyright. That's retained by the music company and the rights holders for the actual songs. The same music clips get licensed and used in various different projects all over the world. SO, Company A licenses a particular song and uses it in their show. Company B and C and D come along and wow they all also license it. It's a popular bit of music.
Company B asserts copyright over the music and attempts to DMCA the music company and several of the other customers also using it. The music company says no, you don't OWN the music, you licensed it. This goes on for a long time until finally lawyers from both sides sit down and clear it up. Company B apologizes and the matter is dropped.
And of course there have been several cases where Sony DMCA'd their own company for using Epic music in other Sony projects. It's a huge company and the branches often have no clue who is doing what. I wonder what the hourly rate is for suing yourself.
