What everyone is debating with you is that you are wrong in picking your target while your base claim of enabling someone, anyone at all, to be a billionaire is correct.

You are wrong in picking Valve or Gaben as exploitative wealthy scum, because Valve is the closest thing to something that is not exploitative corporation, while Gaben as the head and sole person having the final say in which direction to go and which not to go, has been the best guardian of unexploitative gaming entertainment. If you think I'm making these up, please search around to see if you can find the equivalent of these features in any of the meaningfully-accessible companies: Family sharing, Proton, Steam Friends, Steam Network, Steam Workshop, Steam Community Hub.

Steam Family sharing: The current version enables players to have access to the games in other's libraries as long as those accounts are not having access at the same time. The upcoming version allows for access to other's games as long as there are enough copies in the sharing pool. In the age others in the entertainment industry is cracking down accessibility with ever increasing prices, like Netflix' oppression on password sharing or even having access to your own account on multiple devices, please don't tell me this Family sharing improvements by Valve isn't extremely pro-consumer.

Proton: Provides an almost silver bullet, or an easily configurable base template, for gaming on Linux. You can be a Windows or Mac user all you want and never give a thought to Linux, but you can't argue not letting Windows have monopoly over PC gaming by enabling access to gaming on free OS isn't a completely pro-consumer endeavour. It is also open source, so they are not even gatekeeping their own work on this.

Friends and Network: While having no-DRM copies from GOG is great and all, having your games connect to your friend's games, or forming completely random lobbies in seconds, with just a couple clicks requires some always-present middleman. Your no-DRM copies can stay with you till eternity, but you'll have to configure your own methods of connection to your friends outside your local network.

Workshop: Mods hosting for games that support it, and easy installation with 1 click. Yes, there are still free alternatives like Nexus, but they show you ads to meet their hosting needs, so in that sense they are as free as Valve sparing budget from their 30% cut from game sales to Workshop.

Community Hub: A catalogue of all game-related stuff, from guides to memes, troubleshooting threads to feedback, promotion space for developers to knowledge database for players. Open to the whole world wide web and not restricted to account walls or pay walls.

Now, I agree that even providing these services with the best quality-and-features-per-buck option out there, there shouldn't be billionaires while there are starvation and wage slaving ones life this prominent in the world. While these issues persist, having yatches to one person's or a few people's name is an indecent behaviour that should not be allowed in a working social contract. However, when you look at the rest of the companies in the same industry, or even other industries, there are way worse offenders of this wealth inequality that don't even come close to Valve in providing the same quality-and-features-per-buck value, while having billionaires and actually striving to make them more wealthy instead of providing more for the customers and workers.

Case in point: You are not even looking a gift horse in the mouth; you are beating your most hard working horse for eating a hearty meal, claiming you are right in that amount of meal is not needed to survive, all the while letting the rest of your slacking horses raid your pantry without batting an eye. Pressure the others to provide better services per buck, also at a self-sustaining rate so as to not be deprived of it a year later, first.
