I think it's clear that they know that - it was the point of Ryan's post - but have chosen to not address it. As I see it, there is no good that can come (for them) from admitting this "feature". If they say, "Yes, it's a problem but..." then people will latch onto that. If they say, "It's not a problem though!" then people will ballyhoo them. If they ignore it though maybe the commenters will go away...
