I haven't read the full text of the decision yet, but from the parts I have read, it appears as though the judge is saying she doesn't see any issue with Trump muting people, and only is saying blocking is not allowed. It confused me at first, because it seems like if the First Amendment would be applied to this, it would be to make sure that Twitter users can communicate to Trump, not to make sure that Twitter users can see Trump's tweets. But after understanding it a bit more, the actual issue at question here is that blocking prevents the blocked user from doing things like retweeting the blocking user's tweets, which the judge apparently sees as artificially restricting what the blocked user is able to say.
