Well I have to kind of reject the premise a bit, because I don’t think you can meaningfully disrupt capitalism and fascism without some violence. And owning a 10 billion dollar company goes well beyond the necessities of capitalism. And I don’t think propaganda is inherently coerisive and therefore don’t necessarily have a problem with it.

But if I woke up tomorrow morning with billions of dollars and ownership of the largest software distribution platform; I would probaby convert the company to a co-op in which my role in the company and my ability to keep my position as president is decided by a democratic vote, I would send funds to Rojava to support the only large scale implementation of anarchist ideology, I would send money to bailfunds across the United States, I would fund revolutionary worker’s unions such as the IWW, I would ensure the workers of the newly converted co-op were free to engage in mutual aid during business hours, I would implement the ADL’s suggestions for dealing with the hate and bigotry on steam: https://www.adl.org/resources/report/not-game-how-steam-harbors-extremists , I would fund and promote leftist games on the store front, remove right wing propaganda, ranging from openly fascist to Military funded, imperialist propaganda like call of duty, I would work with anarchist activist organizations fighting on the ground to make sure they have everything they need, from secure comms, to legal representation, to food and water.

There’s a lot one could do with billions of dollars and a massive software distribution company, and this long ass list is nowhere near complete.
