Yes, but I hazard a guess it's 30/30/30 fanbois/trolls/real. I would love to be paid to be nasty about Musk, alas I have to decide to do it for love not money. What category does that put me in?
I'm pretty sure he or his PR firm actually does this, particularly on Reddit (where it seems to be cheap to manufacture consensus). A lot of other big business interests too.
As far as people paid to bash him, I doubt anyone has the same incentives.
