And if you own 57% of the properties in Monopoly you still might lose. The standard, for better or worse, in the US for "wielding monopoly power" is consumer harm not market share. If you can't convince the courts customers are harmed by the status quo it'll be a uphill climb.
If this case had any legs, someone would've made progress against Nintendo, Sony, or Microsoft consoles in the past. They haven't, those are more locked down and much easier to demonstrate the price harm when games are $60 and marketed to children.
You say "for better or worse" and I agree, but people don't want to hear that. They want to hear [company I don't like] should be punished and [company I like] shouldn't.
