What I found ironic was, I had to enable flash player to see your Google finance link. I guess Flash is still alive in many places.

I reported some but they did nothing about it.
I work in finance. It's a last resort. It should be front page, but it was ignored for too many years. I think I see it once or twice a year, now.
I end up using my broker for charting, as most of the free ones suck.
1. It's because Google finance is old and probably forgotten. Really answers the OP question why it's not a good idea to kill flash right now.
2. Have been trading for a while and can tell that the performance of that chart beat the hell out of any JavaScript charting tool out there. It's interesting that JS/HTML 5 is all the hype now but it's still lagging behind a 10 year old technology.
