There was the Capitol Hill Occupied Protest. It’s not a whole country going anarchist and no doubt the limited amount of people with the nessisary skill sets to have a functioning society (judging from the food garden they set up) held back the viability of the protest, but in general the Capitol Hill Occupied Protest was widly seen as a wild failure.
It’s an interesting thing to look up on, and I’d definitely recommend anyone who is serious about anarchism to study it for the potential pit falls of an anarchist society that they would need to work out first.
I’d argue that Valve does more than just take 30% as a middle man. Between Steam Input, Proton, the beta built in recording system, the Forums for every game, community system and the marketplace, having your game on Steam is a massive value generator for the consumer and by extension developers.
30% might not be what the industry standard should be, but Valve isn’t just providing a standard digital distribution service.
