I think there is certainly some of this among unknown posters, but I think a very large part of what we see is paid advertising by entrenched interests (and probably some "lone wolves" whose livelihoods are tied to the ICE/Oil/Dealership structure, but are not themselves in positions of power). This would be no different than tobacco companies investing money to advertise for years that cigarettes were not a health risk, and what we see with climate change.
The most vocal on Seeking Alpha (LT, Santos, Tales from the Future), at this point they know a fair amount about Tesla... I really doubt they believe what they are writing. Same goes for what we see from Rupert Murdoch's outlets (WSJ, Barrons, MarketWatch), and I strongly suspect Merrill Lynch/John Lovallo (how could the guy still have his job unless he were doing just what he's been told to do?).

I'm pleased to see they mentioned Lovallo was the most bearish analyst on Wall Street re Tesla.
For anyone who has not seen this, there is a firm called Tip Ranks, that ranks Wall Street analysts based on their past performance. Lovallo is number 3,577 of 3,604 (no typo). From the graph in the link below, it's clear he was covering Tesla at least since 2/21/2013 when TSLA traded at $35.16 and he had a "sell" rating on the stock.
