HN is -in essence- a collection of vocal minorities. Post something on Kubernetes, and you'll get every Linux Sysadmin complaining about how it was better before the age of containers and we didn't invent anything new. Post something on cloud infrastructure management, and you'll get people somewhat angry about its cost. Post something on Electron apps, and you'll get everyone to talk about how C++ and QT apps outshine them in 2022. Post something on crypto, and, you know, it's going to be about how it's not used, too complex, or too energy inefficient.

Good news is, those topics change and become more accepted after some time. It's an endless cycle of Bash-and-Move-on. If something is "too popular", then it's obviously the worse technology ever, according to HN.
