I think it gives Netflix an advantage. When it comes up in front of a judge he'll note the obvious conflict of interest and Trump's idiotic pronouncements, like the fact that he said he will be personally involved, and rule for Netflix.
HA hardly. Balance that against two of the top four streaming platforms (youtube, hbo, disney, netflix) trying to merge, probably should worry about some anti-trust there, but not under this administration.
This will go to SCOTUS, which typically gives the administration preferential treatment. The US's current level of corruption is way too high to assume your scenario.
