Yes, artists have the wonderful choice of being able to sign for one of three labels, with no meaningful distinction between the deals any of them offer, because that's just how oligopolies roll. And they collude^Whave deals with spotify.
Maybe spotify and the labels suck?

They could independently release through Spotify if they wanted to. They're not forced to sign to labels. And even if they were, that's not Spotify's problem.
Getting big in music requires a lot of money and connections that I assume labels make intentionally difficult to access outside of them
And what would you have Spotify do in this situation? Sign artists directly? And draw the ire of those three labels who will immediately pull all their music from the service?
I don't think there is anything Spotify can do themselves
...which is why legislation like the Uruguay bill is a good thing, and important.
