A summary judgment would be nice, but it's clearly much more work and more expensive than writing a blog post. And just for the record, his (and others') blog posts on this subject are the principal reason why I go out of my way to avoid Canonical distributions myself. So clearly the posts are making a difference.

Personally I don't need a summary judgment to see the Canonical is not acting in the spirit of free software. I'm sure there are others that feel the same way.
