The situation drew attention online after users pointed out the irony of the artist being blocked from sharing content from his own show.
That's the thing, it isn't "his." Nothing a worker creates under capitalism belongs to them. His music is a product, and that product belongs to the corporation that owns the rights. The customer doesn't own it, either. They're just paying for the right to attend a concert for one night. Want to see pictures of the show? That's an additional fee.
This seems to be capitalism's final form: you will own nothing and be happy. You won't own your own car, you'll pay a monthly fee for autonomous driving "ride share" services. You won't own your own home, you'll pay a landlord for the privilege of living in their property. You certainly won't own your own music, movies, video games, books or TV shows. Hell, maybe soon you won't even own your own dishes or clothes or home furnishings. Water and food probably aren't too far off, either. Soon they'll own all the farm land and all the water infrastructure.
