If they had not added or changed any features to GitHub for the past 5 years, nobody would be upset, and yet, they keep changing it. It's a website that doesn't need to be reworked every five minutes. I assume the main development teams maintaining GitHubs codebase are ran by managers who cannot justify their jobs unless they deliver new features for the sake of delivering new features to keep their jobs going, and / or in the hopes of getting new people to join GH, when in reality the more they wind up breaking, the more the opposite becomes true.
They severely nerfed their search, I'm not sure why every other major tech company (Google - Search and YouTube) keeps breaking search for everything when it was working fine previously.
What's a bigger joke is Microsoft has Azure DevOps which looks like it might be abandoned? But then you also have GitHub... My least favorite thing about both is the ticketing system, I cannot believe that I'd ever utter the phrase "I miss Jira" when every Jira project I've ever been in had been so inconsistently setup, every, single, one.
