I rather think that the Mozilla decision is blindly based on a more widespread $75000 audit from Webtrust, which CAcert cannot afford. The independant audit requested them to make changes that were not required from other certification providers.
That doesn't change anything for our decision. The point is that using CAcert on Savannah will not help much to get CAcert accepted by Mozilla. It is a sacrifice which is not even effective. And just because Mozilla is showing a warning to users doesn't mean we have to abide: they is also a warning that we should install Adobe Flash after a first install, and hopefully we won't be similarly influenced. We consider Adobe Flash unethical, but we do not consider non-CAcert certifications unethical. We should continue supporting CAcert in other ways, but we should get for Savannah a certification that the widely used browsers accept.
