"It's not the platform holder's job to make [third party games] successful." - Robot Entertaiment CEO

See I can agree with this. With PC you have no platform owner since it's open which leaves those third parties to put in their absolute all and make sure the game works and sells. That is honestly how it should be for all the other platforms as well, those parties have to work for their keep, work for the sales and success rather than thinking they own the industry and thinking they are owed the sales and success along with free rides.

You could, kind of, say Valve is the platform holder of the Steam platform.
