In most cases, they couldn't make that decision even if they wanted to. Only independent artists and those that are so large as to have enough sway (Niel Young for example) would be able to. The vast majority of artists you probably listen to don't actually own the rights to their own music.

So let the rights holders make the decision? They would never. Music rights exist for them to extract profit above all else. They don't care about preserving culture or legacy. Which is why it's important that somebody does.

Did they get to decide when their music was pirated and sold originally by Daniel Ek?
