I'm also curious about this. It seems like the ASL drivers are a bit of a loophole. What happens if later Rethink decides to relicense their drivers as AGPL with a commercial option for businesses? Can 3rdparty drivers be ASL or is that a violation of the AGPL?
We guarantee that we'll grant anyone who wants to release a driver a more permissive license. We're also happy to do it in writing, both for driver developers and users.
Theoretically we can stop doing that in the future and keep changing the protocol, but that would alienate all of our users. That would be an insane decision, and we'll never ever do it.
