The limiting factor here is that unlike stocks, it's not safe for a public figure to say bad things about Bitcoin. It would be like a public figure saying bad things about Nazi Germany while living in Nazi Germany during WW2. Bitcoin is more like a country than a company... Except it's even more dangerous because all its citizens are anonymous; they operate with total impunity. They could remove anyone who is an obstacle to the Bitcoin price and nobody would know who did it. Worse than that, any attempt at investigating the crime would be anonymously bribed to a halt. Not sure if it's like this yet, but seems like a definite possibility.
