Well this was very much expected wasn't it? A judge has ruled in the case of Wolfire versus Valve to dismiss the case.
As a brief reminder of what's been going on - Wolfire Games took Valve to court over a couple of things like: the 30% cut Valve take, and an apparent clause that forces developers match their prices on Steam to other stores if they release their game elsewhere. Valve of course moved to have it dismissed and now a ruling has been passed down.
In the new filing on November 19, the judge has dismissed and denied the case in part, giving Wolfire leave to amend their case, which going by the documentation Wolfire requested and it has been granted, so we might see Wolfire back again with an amended case at some point (they have 30 days).
Going over why it was dismissed, the ruling makes it pretty clear, mentioning that Valve's store fees have remained a constant, even with competition and even when they weren't the "dominant" force in the market. It additionally mentions an older case with Sommers v. Apple, where Apple had a 99 cent music download fee:
"There, as here, the price remained the same throughout, even during periods of intense competition in the marketplace."
It also notes that other stores have charged less than Valve and failed:
"The market reality, at least as plead in the CAC, is that, in spite of Defendant’s 'supracompetitive' fee, others who charge less have failed, even though they had significant resources at their disposal."
When looking to the footer notes, the filing brings up the "substantial" consumer base on Steam and favoured features on Steam, noting the backlash that generates when a developer chooses to release elsewhere and not on Steam. It wasn't named directly but they're hinting at things like the Epic Store here, which is interesting to see it used like this, so it's actually clearly helped Valve's defence here. Competition is good, obviously.
On the subject of the apparent most favoured nation clause, which is what Wolfire claimed Valve used to force prices to remain the same on Steam as other stores, the documents state the complaint lacks the allegations to actually back it up. Not only that but this too:
"If anything, the facts provided by the CAC, at least with respect to output, suggest the opposite—a consistent increase in the number of games available in the market and on the Steam Platform."
