But in my opinion, Elon Musk is a very smart man who not only sees, but has reaped massive value from Twitter. He is notable for tweeting misleading information to affect the stock price of his companies. These actions resulted in a lawsuit from the SEC in 2018.
The ripple effects of stock manipulation are hard to directly tie to the concept of "awful for society". But it certainly feels like when money is given one place, it is taken from another. When that transfer of money is based on misinformation, it creates pain. I personally am doubtful that the billionaire feels any of it, but someone else will.
I also don't believe that Musk has learned any lesson from the lawsuit either. He is currently trying to fight the tweet pre-approval stipulation in the courts. Putting a financial investment into the company to me personally, looks like someone who has found, or is looking for a loophole.
