First, the short sellers getting taken to the wood shed absolutely deserve it for placing such an idiotic bet. The short positions outstanding are 150% of the available shares even today. Its a short squeeze even more than its WSB pumping it. And apparently the short sellers just keep coming back for more. They can play that game if they want and I dont feel bad that they lose all their money.
Second, theres no such thing as "short seller pressure". The act of shorting does not lower the price of a stock mechanically. You could argue they are forming a negative narrative but I would call that fair game. You're allowed to say a business is crappy.
Third, WSB pumping and dumping stocks is scammy and definitely not good for the markets. Thats just a mechanism where the early pumpers clean out all the idiots who follow their trade.
