The main copyright holders I know are musicians who write and record their own music. One is East Bay Ray, the guitarist for the punk band, The Dead Kennedys. Another is a trio of angelic folk singers, The Wailin’ Jennys.
In both cases they have seen their revenue from recordings drop down to negligible numbers over the past 20 yrs. This means they have to tour much more in order to be full time musicians. Ray is 70 years old. The Jennys all became mothers over the past decade. Touring is much more of a hardship when you are a mother, and sometimes it just isn’t doable.
Will this new article 13 law help them and other copyright holders earn their living from their recordings? Not unless it succeeds in forcing YouTube to stop allowing people to watch copyrighted material for free and they succeed in stopping stream-ripping sites from searching them for items to rip. I do not see how they are going to accomplish that. As of last fall, YouTube had done nothing about it.
Meanwhile, smaller sites may soon be required to pre-approve posts and links uploaded from their users, an expense many cannot afford. And this in the service of stopping piracy that hardly occurs on small sites anyway.
