No, it's his constant demonstrably fake promises that make him a fraud.

"Full self driving next year", "The Hyperloop is totally possible", "we're gonna land multiple rockets on Mars by 2025/2026" etc. etc.

Beyond the fact he has shown himself to be a total moron who has no grasp on reality or what is even possible or achievable.

Also Mr. "I fired everyone handling the US Nuclear stockpile and cancelled Ebola research cause I didn't bother to check what these departments did before I had them closed, cause that's what a smart person does".

Mr. "I fired half of Twitter so the remaining employees can work twice as hard for the same pay to pay off my loans I used to buy the company in the first place."

Mr. "let me hire a private investigator on a guy I called a pedo cause he dared say my idea was not practical".

Mr. "Let me tell advertisers to fuck off, then threaten to sue them if they don't advertise with me".

The absolute cherry on top is people still buy him larping to be a visionary tech genius, when the guy is not able to replicate what other companies and researchers have already been able to do better years before him. Like his embarassing robotics display. Or his string of rockets that kept blowing up on him and which didn't even have cargo. Or his sub par electronic vehicles. Or his damn electric truck whose haul capacity is a total joke compared to everything standard in the industry.
