Musk was the primary initial investor in Tesla when it was company with 3 "employees", was chairman of the board and directly involved in the design of the Roadster. He didn't take on an operational role until he forced out the first CEO for allegedly lying about the financials. Musk is certainly more than just an investor in Tesla, it seems pretty nitpicky to argue he is not one of it's creators.

Musk has been the only CEO of SpaceX since he founded the company. Gwynne Shotwell often doesn't get enough credit for her huge role in making SpaceX what it is today, but to say Musk isn't one of the creators of SpaceX is absurd.

Musk has made plenty of bad choices and done unethical things that deserve to be criticized, but that is no excuse for the level of ignorant, misinformed hatred that is directed at him.
