Honestly, I would just call him malicious, not paranoid. He has made it clear that he hates public transport, as in the idea of using it (in that it is crowded and such...). This is of course funny because we all know that Musk has never in his life used a regular city Bus or even a train. I think it is safe to assume that he would do something like this not for monetary profit, but simply out of spite.
We are talking about a guy that pays tens of thousands of dollars just for the attempt to discredit and harass a rescue diver he doesn't like... [1]
