Well I suppose by asking the question, you may already be tipping your hand -- that you do find it significant.
I only see it for what it is -- people want their privacy when online, when that's an option available to them. If I didn't think people's privacy was important, I'd disable that option. But since I do, people can and do use it. And that's perfectly alright by me...
I try not to read too much into things, unless I have a lot more information...
