To be honest I am not surprised that flex is going open source and was just talking about this with a friend of mine a day or so ago. I figured it was only a matter of time. Logically it makes sense and I think it's a smart move on Adobe's part. In doing so they open up the doors to developers from all walks to jump in and get their hands dirty with flex and effectively ramp up development on Flex. This in turn leads to better adoption of the platform, better components, integration etc etc. Plus from a business standpoint they're still making money with FDS and going to increase the demand for said product with greater adoption of Flex.
All the same kudos and thank you to Adobe! - Kyle VanVranken
