Only because he didn’t declare himself candidate. Actually the vitriol seems very much oriented, in French newspapers, it’s unnatural.

He doesn’t do a tenth of Jeff Bezos’ evils and journalists are not talking about Jeff Bezos’ actions on national TV.

He's much louder than Bezos. The upside (EV's going mainstream, reusable rockets, full-globe high-speed low-latency internet connectivity) of Musk also seems bigger.

The amount at least is very disproportionate. He seems to get a more vitriol than Xi Jinping, the Koch brothers, Rupert Murdoch, Andrew Wilson, Bill Gates, the Sacklers, Hillary Clinton and Larry Elison combined. Despite far lesser crimes (by the standards of those who dump on Musk).
