It's not the judge screwing up, it's you. You are showing incredible "tech nerd" bias by thinking Lineage or Graphene are "competitors" or that they could or will matter. They're nerd hobbies, they affect less than a hundredth of a percent of Android devices, and do not matter.
What the judge did ban is a bunch of things Google did you may not have even realized they were doing, like the terms in the MADA agreements all manufacturers like Samsung, LG, etc. were required to sign which prevented any competition and required Play Services. The judge also banned revenue sharing agreements with manufacturers and mobile carriers used to prevent companies from using different search engines or app stores.
Nobody, figuratively, will ever care about some custom ROMs. But the judge has broken all of the means Google was using to control device manufacturers.
