No, they sued as an answer against Valve's threats and actions, nothing really to do with customers, but Valve using it's power to dictate how they can sell their product in a way that does not create competition against Valve.

It's literally called anti-trust lawsuit.

EDIT: Honestly dude, I think we should just agree to disagree and finally end this convo. You're obviously not convincing me and I'm not convincing you, so it's a dead end of back and forth.
