You mean in 2021 HTML5 was barely supported by browsers? Adobe ended support for Flash Player on 31th December 2020.
For comparison, the original HTML5 W3C recommendation was retired in 2018 and even Version 5.3 was retired less than a month after Flash Player was retired.

Functionally. Functionally. I said functionally for a reason. I didn’t just add that word in because I liked how it looked.
When was the last time you actually saw flash content?
Browser extension support deteriorated. It never worked on iOS. People stopped making flash content because folks couldn’t view it long before it officially became unsupported.
