Their change in stance was welcome. They didn't have to rewrite the blobs, though. They could just set them Free, or release enough info so that others can rewrite them. Surely they have either if not both.
My old ATI card works fine only if I blacklist the radeon driver. I had it completely disabled for a long time (it didn't work after replacing the blobs disguised as sources with empty arrays), and when the blobs were moved out of the tree, I tried again, but then I ran into the interrupt storm, figured it still wouldn't work and moved on.
