Musk is, to say the least, polarising, and thus attracts a lot of people who take either highly favourable or intensely sceptical stances on everything he says. These two groups then feed off each other - those critical of Musk often feel compelled to counterbalance what they see as overly charitable interpretations of his statements or the actions of companies associated with him, and vice versa I guess.

In this particular topic, Musk has a history of being... opportunistic to disasters and tries to 'help out' to various degrees of success (see his weird mini-sub saga for the thai cave rescue, and Starlink's involvement in Ukraine/Russia war).

Personally, I think he's a terrible human being who uses his platform to spread vile hate which is incompatible with a modern world, and I tend not to separate the art from the artist (if you could call either of them that). But otherwise I'm not brigading out here.
