The VM is open source, the frameworks are open source. The language specification is open. The only thing closed are codecs (many of which are licensed from other companies and can't be open sourced), DRM stuff and platform level code that glues everything together. On the other hand, there are open source versions of swf players that Adobe actively promote. Unfortunately, community involvement (developers and early testers) in all these projects have been low. My understanding is that people within Adobe (and there are many who like Open Source) have no evidence that open sourcing more stuff is any better for the player, since the community hardly gets involved. Adobe did launch a 64-bit Linux flash player on Labs. Most 64 bit users never used it, sticking with the nspluginwrapper method instead. I'm sure more community involvement with existing open source projects at Adobe would pave the way for opening up of more stuff.
