After it seeming like Valve might have won in the lawsuit from Wolfire Game, the story appears to be far from over.
Last we heard it was in part being dismissed, seemingly like Valve had the upper hand as Wolfire didn't have sufficient evidence of their claims. Now though, as reported by Bloomberg Law, part of the case has been allowed to continue as the judge now seems to believe that it's "plausible" Valve uses their position to mess with the market in their favour.
The issue here, as before, is that Wolfire claim that Valve and Steam use a "most favoured nation" clause with a mixture of "written and unwritten rules" to "prevent price competition from rival storefronts". Wolfire are again sticking to their claim that Valve would remove games from Steam that are found cheaper elsewhere, noting that a "Steam account manager" told Wolfire that Valve would "delist any games available for sale at a lower price elsewhere, whether or not using Steam keys" and it's this that has the judge saying "These allegations are sufficient to plausibly allege unlawful conduct" and so it's going to continue on that point.
Other claims like the 30% cut Valve take being "supracompetitive", and another antitrust issue of Valve tying together the Steam Store and Steam Platform seem to be dismissed.
Whenever we hear what happens next, we'll let you know.
