Don't know about the rest of Adobe, but the flash team is heavily intertwined with mozilla and google developers. Go sample irc.mozilla.org sometime.
Fun fact, the first JavaScript was written by a Netscaper in Lisp. The first ActionScript was in Standard ML, and now both guys work on ECMAScript :-) ActionScript's engine powers Mozilla's JS engine (yes, flash and firefox engines off the same code base!) and the Lisper guy works on V8. Get into the javascript scene and you will find the intellectual incest that is hacking.
