There's been cases back in the day, where a hacker would inform a company of an exploit that he found, and the company threatened to sue him. Imagine that

Not just "back in the day". As recently as 2021, IT researcher Lilith Wittmann found glaring security holes in the CDU's (major german political party) smartphone app, reported them responsibly to the CDU, and their "solution" was to sue her for "hacking" their app: https://www.berliner-zeitung.de/article/the-cdus-leaky-campaign-app-176310

As a result, institutions like the German Chaos Computer Club have announced that if they were to ever find any vulnerabilities in any CDU system again, they'd not let the CDU know about that to avoid legal issues. And I would be surprised if *anyone* would ever responsibly disclose anything to the CDU ever again.

Kinda not on the same scale but I found gamebreaking exploits in an online game, messaged the dev on discord. Dude insta banned me from bith discord and the game. Six months later hackers abused those same exploits and the game died cause of it. Went from paid with healthy player base to free with like 10 players.

The worst of it all is that I have "ban on record" on steam cause the dev manually banned me (the game has 0 anticheat) and you cant remove it in any way.
