yeah it was "all the rage" in the early 00's up to like the early 10's. Pain in the ass to build, even worse to maintain and update. but EVERYONE wanted a cool interactive flash site. It's just trends with companies. I remember after flash it was all paralax. everyone wanted paralax. thankfully that was a lot easier to build since it was just HTML5. but yeah web dev trends are annoying because you're constantly having to learn new stacks that you know will become irrelevant in like 3 years or less once some middle manager discovers something "cool".

I'm all about using Astro + Tailwind because it reminds me of building Geocities sites and I like that.
