Starting a post with "I know this is voluntary work, pitch in or shut up and all that ..." doesn't make the quote you're attacking untrue. For what I'm paying for Mint ($0.00) and what I get out of it in terms of productivity, I find it quite a decent distribution.
The problem is that Mint allows users to trust it. It would be better if they didn't work on the distro at all if they're not going to take security seriously.
People on HN become furious about antivirus programs and routers and whatever else that are discovered to be laughably insecure. An OS is no less of security product than A/V or a router. In fact, it's the first line of defense for an end user.
