The author makes your point that there are plenty of smaller voices out there. However the commissioners and platform owners are no longer so incentivised to find and promote those voices.

While it's great to go out and see interesting local stuff - we also need mainstream entertainment for when we are not at those spaces during the other 99 percent of our time.

This is the author's point: the revolution was previously televised. Original films, 'alternative' music, street press, small publishers, etc have all but vanished from the cultural landscape.

This has lead to a kind of stagflation of shite. A cultural blight where the sameness of cultural product grows and becomes harder to break out of.
