I think their statement is useful to contextualise what people consider leftism though. Looking at Musk's actual political actions, it seems like leftism (or at least the part that directly affects him and his companies) is when regulators are allowed to ask Musk to stop doing securities fraud with his social media addiction, and it's not entirely unreasonable for him to consider such enforcement a threat (though maybe not "a grave danger") in case it escalates beyond strongly worded letters. I am, by that metric, a leftist. Possibly a radical far-left communist, even.
