As I understand it Gentoo's Symantec change was masked out. Symantec's entire argument is basically that they're such a large (and more importantly visible, they only issued about 5% of the valid site certificates, but they're disproportionately on high traffic sites) provider, so just instantly switching that off will break lots of stuff. I suspect this would very quickly demonstrate that Gentoo's independence is more theoretical than actual.

I appreciate that CACert's processes may feel robust if you happen to know the core CACert people, most of us don't and never will, so what we see is just another flailing volunteer group. Ten years ago CACert looked like a reasonable way forward, but today it does not. Maybe if CACert had been in the game much earlier, say in 1998 not 2003 then they'd already have been included in key stores prior to Honest Achmed and the CA/B and so then they'd be _inside_ the tent making rules for newcomers, not outside desperately playing catch-up.

In terms of competence, I see basically the same sort of errors made by CACert as at Symantec, and I feel the same way. Yes, in principle you can take a bunch of tools and know-how and do whatever you want, issue whatever you want, and it will all work out fine. But you will very likely make lots of mistakes if you do that, so I _strongly_ recommend you instead put the effort into having machines doing just a handful of things very well, and then sit on your hands. At one point Symantec tried to create a custom tbsCertificate and in doing so they erroneously signed it, even though the _whole point_ of the exercise was not to sign anything, when you read transcripts of CACert trying to follow simple instructions for a non-standard procedure it looks much the same.
