i think adobe's position is: if they completely opened up the flash format, then they couldn't make any money off of it. they give away the player for free, so they make their money from the developer tools. if they opened up the .fla format, then they'd get killed by competitors, because flash cs3 sucks. so it wouldn't help them any to grow the flash platform, if they lose their ability to make money off of it.
