Before the Microsoft take-over GitHub was fairly stagnant for quite a few years. Remember not being able to meaningfully copy code because it would also copy the line numbers? Kind of ridiculous that took such a long time to fix. But for the last few years ... yeah, I feel it's just getting slowly more annoying. I sometimes genuinely wonder if the people working on GitHub actually use it themselves.

I've tried reporting some really obvious and annoying bugs to GitHub, and they even never got fixed, took months to get fixed, or got fixed and then broke again a while later. I stopped bothering.

GitLab is still tons worse, so there's that.

As for React, unfortunately there is a contingent of frontend developers who seem to think that everything must be React, that React is the only possible answer, and everyone not using React is a decrepit developer and probably a decrepit human being and quite possibly a registered nonce, and will generally just forever bang on about React until the entire world has converted to React. Your frontend will be assimilated.

React is not the only tech where this is a problem, but it is probably among the more frustrating because as a user I don't really care what language or database you use as I typically don't really interface with it, but I do interface directly with your frontend.
