Steam unfair to Humble?  maybe , but I've never had Steam charge my credit card and then not be able to deliver a game key (for weeks mind you.),(reply>), Steam is apparently monopolistic which is why GOG, Origin, Epic Store, Microsoft Store, etc, just don't exist and that Steam will automatically uninstall them. I really doubt they have much of a legitimate claim towards steam being monopolistiic, more so with how Steam can be linked with GOG and origin linked with Steam. Basically humble bundle doesn't like that valve takes a 30% cut, that is all it's about and their lawsuit relies on claiming steam is a monopoly which will be near impossible to do given how it isn't abusing market position to keep competitors down.
