Comment 8 for bug 681596

It sounds like a discussion needs to be had about this, probably in the Community Council. I can't speak for Canonical trademark policy, I am just able to suggest that relying on Launchpad's code browsing features as a way to serve CSS, is a bad idea.
There must be a solution waiting to be found that gets the community the theme resources they need, in a way that lets them use the hosting platforms most suitable to them :)
