Because Gamestop is a business that is in the process of adapting to changing market conditions, which generally requires capital, and when market analysts go big on shorting in public it depresses stock price, and issuing stock is a major common method by which businesses raise capital.
As another example, lots of people assume Elon Musk got mad at short sellers because he took it personally, when in fact they were fucking with his ability to raise money he needed to ramp up production and meet manufacturing goals.
These things don't happen in a vacuum. Large funds making public bets against a company have a material impact on that company's liquidity.
Short-sellers are part of the free market. They are how the equation balances itself when trying to find the "true value" of a concern, or at least an approximation thereof.
Obviously the person who owns stock, or is set to earn billions when the share price reaches a certain level is going to be adversarial to someone whose actions result in the share price being depressed - even if that is the fair value.

There are always bigger fish - and if the public bet is wrong, someone can, and will earn money at the funds' cost.
Edit: shareholders dislike shorts the same way employers dislike employees sharing salary information; it's a losing proposition for them, but a fair one.
I would like you to show me where this free market is, because it certainly isn't NYSE. The minute anything unexpected happens we're hit with trading halts, brokers riding the line of insolvency, SEC investigations, and congressional freakouts.
This narrative that GameStop is actually a good company and it's turning around despite all the short interest is pure bologna. Worse, it's intentionally misleading and often espoused by people who have a financial interest in the company. It's crazy to see people in this forum, who are typically tech forward, hype up the business model of selling physical copies of video games.
This is a common reaction to people who haven't followed Gamestop for a while. Cohen and RC Ventures bought in a while ago and have been pushing for the company to pivot out of the brick-and-mortar focus. This is why 'people who have a financial interest' are talking this way. Everyone involved recognized this would be an expensive proposition. Then the short sellers showed up.
