It doesn't help if they don't offer the same GUI debugging capabilities, and polyglot support as CUDA does in its current form.

Or AMD could simply knock off the binary blobs. The DRM excuse has always been weak, because it is a tiny fraction of the total firmware blob - and it'd be easy to make it so that the legally hobbled hardware decoder simply errors out in cases where the end user chooses not to load the DRM blob. Boom, no more dependence on AMD interns. I've been following their commit logs pretty closely for a year now, and I frequently see some amazing accidental admissions about the left hand (software team) not knowing what the right hand (hardware team) is doing. During one very frustrating series of patches it was difficult resisting the impulse to say "Go get your dad."
