artists are scarce too, and without them there is no content to host and compute
the artist generally has to accept the offer from a delivery provider, or choose another one that they find more favorable, it's just the nature of art, and why for much of the 20th century it was monopolised by the publishers, back when delivering the material had a high cost and risk of non-marketability
a lot of artists do themselves a disservice (and inventors also) by trying to use copyright monopoly delivery providers and end up almost nobody hears about them and worse, their material doesn't sell and their contracts are cancelled
then it all ends up being given away for free anyway because this restrictive, customer-punitive delivery service simply was a bad choice for the artist, this still doesn't invalidate that there is a market price for delivering content and thus content itself, as a factor of this production, has a value as well
content that is popular earns more for the artist, and this also benefits the provider who is then also well known for this artist
