> ending distribution of a copyrighted work
That's not what the article was about, as I understand it; the music concerned is generally still being distributed in its own right, but the show's license was for a limited period (and/or distribution channel).
> we could just move to a mandatory licensing regime
I'm not sure a mandatory licensing regime would be a good answer for anything; or at least it could be really hard to design one.
Suppose the next populist presidential candidate wants to use some popular artist's latest song at rallies. Does the artist not have a right to decide whether to license that?
Suppose Pornhub wants to license Disney's content, to stream alongside the other material they provide. Shouldn't Disney have a say in whether to allow that or not?
