Right, most of the complaints people have about Zuckerberg is that he's a stereotypical tech bro ceo lacking a moral compass.

People calling Zuckerberg a lizard person or robot mostly come from how he talked and acted when under intense public questioning by legislators regarding user privacy and their business model. That's a high pressure situation where he was coached on what he could and could not say by legal to minimize the fallout, so his awkward expressions and stilted speech are understandable.

People don't like him because he's a ruthless ceo, and that requires some level of sociopathy pull off. Musk, on the other hand, actively antagonizes people and seems to thrive on controversy. His primary goal seems to be ego-driven, unlike Zuckerberg who's solely in it for the money.
