Adobe open sources Flex SDK under MPL

andy_from_nc writes: "Adobe announced that they are open sourcing their Flex SDK under the Mozilla Public License incrementally by December. This move comes on the heels of Microsoft's announcement of their Silverlight and Adobe's CEO's criticism of it. The move will likely please other open source developers who use Flex like me and offer hope that we'll see a full open source version of Flash one day. You can read Adobe's FAQ on the move as well."
