I'm sorry, but no shit? You frame it like there's some insight or conspiracy theory in there.
Again: What is your issue with this? The market has rules, some companies skirt them or outright lie. The size of the market is too large to regulate with our current mechanisms and short sellers fill some of these gaps for a profit. It becomes an issue if the short seller is wrong and causes harm to a company undeservingly, but you haven't proven that case here.
Publicity helps move the market which is how they make money. Why do you think that make [him|them] illegitimate? You've not explained this part. It seems to me that you've got an axe to grind with short sellers in general. Hindenburg seems to clearly be "the real deal", whether or not you approve of what "the real deal" is.
There are so many bad companies that are public today, they really need somebody nipping at their heels.
