At a meta level, I consider Musk and Trump both to have the same approach to media: say whatever you want to create publicity. Words mean nothing, in the sense that there are no repercussions large enough to outweigh the created buzz/fame. Outrage works extremely well to that end (look at this thread.)
Because he says things helping both extreme sides (lovers and haters,) all they have to do is latch on to whatever fuels their fire, and ignore the other words. And it is well-know that confirmation bias is a thing among humans. This causes polarization that fuels the debates, creating a spiral of even more debates, buzz and fame. Even sparks meta-debates.
Edit: Another side of this is that it seems that everything must be classified as good or bad. Both on HN and elsewhere, commentors go to extraordinary lengths to argue why something has one abstract label or the opposite. Does everything have to have emotions assigned to it? Does everything have to be categorized in the very coarse good and bad buckets? It would be nice to read comments where the author tries to explain both sides, instead of just arguing for one.
