> open source is getting screwed over

It may have been "screwed over" if there was no access to the oss game. But you can still download the game from their website. They just do not want that these appear as competitors in steam/gog platforms, so they bundled the oss version. Both sides thought this was a reasonable resolution. Thus I don't see "screwing over" here.

Open source is a culture that includes its users. Open source is getting screwed over because at the first whiff of a capitalist losing a buck open source retreated and hid.
