What Happened to HackerOne?

HackerOne, founded in 2011 as a platform to safely connect ethical hackers with companies for security vulnerability research, experienced a "golden age" from 2017-2020 when it prioritized hacker needs and regularly hosted exclusive live hacking events. According to an experienced bug bounty manager and researcher with firsthand knowledge, the platform appears to have recently declined from its original mission, prompting concerns about its current direction and wellness.
