Well, I am glad that Adobe is committing to fixing the problem, but it is not 
something I would rely on happening in all cases.

The majority of Fedora users also need support for certain proprietary video 
and audio codecs, but we stick to our guns when it comes to that.

That would require us to ask people to agree to the proprietary Flash license, 
which is not, in my opinion, philosophically sound.  It is one thing to accept 
bug reports regarding Flash and forward them to Adobe; it is another thing 
entirely to start asking Fedora contributors to test it out.  As I said 
before, Adobe released proprietary software, so Adobe should take on the 
responsibility of performing QA on the platforms they want to support.  If 
Adobe wants to target Fedora, then let them install rawhide and beta releases, 
and make sure that the Flash plugin is still working.
