Matt would be allowed to charge for access to Wordpress.org. It's his property. What you can't do is:
make a service publicly available and then threaten a company that it needs exclusive terms
In the lawsuit the judge asked Automattic to come up with a price for access to Wp.org and Matt did not provide an estimate.
>we think we're going to need either ask that you setup local mirrors, or we can maybe arrange a pay as you go deal.
In the lawsuit Automattic asked the judge to force WPengine to shut down their mirrors. They want control over the system. Which is also legit, but legally you can't offer public terms for all and then threaten a company with "the nuclear option" unless they agree to a separate set of terms for 8% of revenue.
Wordpress.org could have terms that allow companies to setup mirrors, but they explicitly don't want this, and wordpress.org is hardcoded into Wordpress Core.
