This is really what people mean by having compiz/beryl default in fiesty. The decision is actually not related to compiz or beryl. It is all to do with whether or not binary drivers should be enabled by default. This is NOT a GPL license issue. I suspect the drivers will be downloaded separately as per normal, but it will be part of the installation and enabled.

I have made it a poll to see what people think, I tried to narrow down the question to what it is really about.
