I'm no fan of Musk's, but the claim is moronic.
However, the real tweet it is based on is pretty weird:

Musk is apparently both a free speech absolutist, and worried about a 'mind virus' that is causing civilization to commit suicide. Which doesn't feel particularly consistent.
As for Musk, I certainly enjoy armchair-psychoanalyzing him, but I assured @dang the previous time I indulged would be the last :)
