My two heaviest marijuana smoker friends are 100% sure that any study that mentions some detrimental effect from marijuana is part of a big-pharma conspiracy. Their argument is that "it's a natural herb, it's impossible for it to do harm".
Sounds like Tesla fanatics and the phantom ICE manufacturers they think are out to get them.
Pretty sure different companies competing in similar sectors aren't above stoking FUD about their competitors, no matter who they are or what industry they are in.
I heard Tesla fans speculate that coverage of Tesla's cars failing is driven by a secret cabal of short sellers and car manufacturers that are conspiring with the media, which apparently is also out to get Tesla.
