Magical? Those are some rose tinted glasses. Having to install a binary blob from a free-software hostile vendor that wanted a monopoly to load a website was always ridiculous ask. Flash was a constant embarassment of RCEs vulns and virtually non-existent Linux support.
The overwhelming majority of computer users simply DO NOT CARE about things like "install a binary blob" or "free-software hostile vendor" or "non-existent Linux support". They installed the plugin and got a way better experience.

I wonder if anyone has done an analysis of Flash versus Javascript (or other browser technology) vulns over their respective lifespans.
I remember the time of browser plug-ins (not “extensions”). Everyone happily installed Flash, and the Crescendo midi plugin, and multiple other in-retrospect-ill-advised plugins to enable fun stuff to work in their browser.
The “everyone hates Flash” stuff came later. It served a purpose for quite a while and people loved it. Newgrounds was a place of magic.
