This seems like such a nothing case. Steam is optional. It’s optional for publishers to use, it’s optional for users to install. Steam provides many many benefits for even free games or games not purchased on the Steam store.

Any publisher can publish their game on their own site, on other stores, on physical media. Even though Steam is dominant, you can buy games somewhere else as easily as you can download and install Steam itself.

I hope this case gets thrown out.

I don’t have a problem with Steam but if they lose, games can get cheaper, and/or game development becomes more lucrative. You can’t lose by looking into the case and not throwing it out.
