Facebook, Apple, Amazon, Netflix and Google like this. (Microsoft also does.)
The illusion of decentralization given by "you don't need a publisher, you need Amazon" and "you don't need marketing, you need a Facebook page" is one of their most successful creations. We haven't gone decentralized. We've given even more power into singular technology monopolies and eliminated many of the intermediaries that gave us actual choice of who to ask for publishing and how to market our products.
Now it's "sell it on Amazon"/"market it on Facebook" or you just don't exist at all.
