if anything, it shows that Twitter is able to tell the difference between a harassing troll, that requires moderation like any public communication platform on the net needs to moderate, and the other being someone who needs their right to free speech defended when criticising the government.

I wanted to downvote you but did not because I suppose this is an important question to ask and it adds to the discussion. However, the way you frame the question, the feigned incredulity, almost makes me reconsider. Unless you truly mean you're unable to spot the difference between the two (in which case I don't need to hear about it).
