Thanks. So TLDR:

1. PMFN (Platform Most-Favored-Nations clause): Valve forces publishers to price games on other platforms at the same price or higher than Steam. This is an anticompetitive monopoly because publishers can't sell the game at lower prices on platforms with a lower cut than 30%, which would improve competitiveness. Very valid point
2. Keys that publishers can sell on other storefronts are limited. This point is moot. The fact that Steam allows you to activate a product that was purchased elsewhere and then use their infrastructure to download the game is way more than they have to do. They can completely make the rules here as this is basically a free service that you get from Valve.
3. Some murky points about Valve policing review bombing that isn't explained properly.

Valve devotes only a small percentage of its revenue to maintaining and improving the Steam Store, and dedicates very few employees to that effort.

Okay yeah I was annoyed that it took Epic's store to make Valve update their ancient UI, but Proton has gone a long way to improving my opinion of them (and it's open source to boot).

Also is a shame that the court won't have the background to know that invoking EA's complaints about anti-competitiveness and price gouging is so completely laughable.
