HTML5 is now the preferred option.
Preferred, yes, but Flash is very firmly entrenched. There are millions (billions?) of websites out there using Flash and they won't be recoded overnight – or anything like. This site is just one of them.
Like you, I have Flash turned off but I have the browser option set to ask me if a page requires it. I then either move on or answer "yes this one time" or "yes for this page from now on". For the archive here I've used the latter so it invokes Flash automatically.
