the main reason this lawsuit is even moving is that leaked emails that valve does indeed force price parity even for non steamkeys, I really doubt those leaked emails since I have seen first hand plenty of cases of games having different prices, sometimes even extreme differemce in pricing, for example, mindustry is paid ln steam but free on itch.io, google play store, fdroid

many other, even more questionable claims are raised withour evidence or drawn very dubiosly in the law suit

this lawsuit is pure theatre

beyond this, plenty of companies have even more and clearly anti competitive with their practices extending beyond game selling and distribution, namely apple and google, who control respectively iOS’ (very genericly poorly named) apps store and play store who clearly display anti competive behaviour and are clear monopolies
