The driver is secret because "secret sauce" performance enhancements, which puts the entire burden on AMD when the community wants to get things working. Meanwhile, they note the open source driver has a lack of people working on it.... probably because the closed source one is the only really useful driver and the open source one is futile.

Sounds like a good reason to keep it hidden to me. Didn't want to buy a Radeon anyways. Nothing about this 'idea' sounds like Linus will approve either. I'm not a fan of Nvidia or AMDs approaches right now, they're both half-assed and embarrassing.
