I think the evidence is overwhelming and admitted in some cases that the government used social media to push a single message endorsed by the government and suppress all contradictions/opposing information, questions about, or disagreement with that message.
I wish the source used in the OP was more clear about that, i.e. the court was forbidding the Administration from using social media in a way that suppressed freedom of thought, belief, speech instead of the initial impression that they were forbidden to meet about anything.
If you read the article, you'd know that's not the case.
