I don’t understand. I put out a takedown request for something I don’t have the copyrights to and as a result the real copyright holder loses their copyright? How is that fair?
You use my song in a fair use way
I claim you are infringing my copyright
you challenge, I fail to prove my case
I lose copyright on the song and it enters the public domain.
I own the copyright on the song X.
Person A uses the song X in a fair use way.
Person B claims A is infringing.
Person A challenges and wins.
Then I lose my copyright, without any involvement?
That's so disproportionate that you might as well just abolish copyright.
Also, most of the world doesn't have fair use like the US does, though many places have similar but weaker provisions in some respects. US fair use law is somewhat controversial, because it arguably doesn't comply with international obligations.
Ideally that's what we would do.
