Humble mostly sells cd keys to steam games and almost all itch games are free. How is somebody going to pay their bills with that as a marketplace? How easy and cheap do you think game dev is? Do you think that indie devs deserve to be able to pay their bills?

Its disingenuous to state cases which arn't applicable to this case (humble selling keys when they also sell full games without keys) (itch having free games when they also have paid games), and then using that as a strawman of what I'm suggesting

Is it Valve's responsibility to ensure they can pay their bills?

Its Valve's responsibility to make sure all dev's on their platform are treated fairly.

Do you think this would happen to a major publisher? That support agent would never pull this kind of thing with a major publisher as they would be afraid of losing their job.

They are picking on a no-name indie because they know we have no agency on their platform.

Yes, this is what I am on about. Game dev's need Steam to make a living. I don't think its right to allow steam support to arbitrarily "retire" games at any point in the games lifecycle for any reason of their choosing.
