Nobody would be complaining if they lost a ton of money on a stupid trade. In fact they would be posting loss porn on the front page of the subreddit and laughing about it. In fact, some WSBers did short GME and lost a bunch of money.
But when the hedge funders get caught then for some reason it's bad and Reddit or Robinhood or the government needs to step in and fix the situation. Instead, we should all be laughing over Melvin Capital's loss porn.
