Drank the kool-aid?!? I worked in the eLearning space, I was a prominent user and developer for Flash/Flex content... there was some interesting tooling for sure, I also completely disabled it on my home computers as a result of working with it.
I had a lot of hopes after the Adobe buyout that Flash would morph into something based around ActionScript (ES4) and SVG. That didn't happen. MS's Silverlight/XAML was close, but I wasn't going to even consider it without several cross-platform version releases.
I agree it should have been open-sourced (at least the player portion)...
As for Silverlight, I mean the technology itself was closer to where I wanted to see Flash go. I'm not sure why you're laughing at that.
edit: as for not being as bad as people describe it... you could literally read any file on the filesystem... that's a pretty bad "sandbox" ... It was fixed later, but there were different holes along the way, multiple times.
