Not that I can find in any hurry, and it's also worth my mentioning that occurrences are decreasing, and I'm not sure if that's because there are fewer people legitimately taking the ad-defensive stance, or whether there's a 'chilling effect' caused by (in my opinion) the increasing volume (in both definitions of the word) of arguments against ads.

My memory also tells me that most of the pro-ad stances on HN have been cagey; justification within a certain set of privacy-respecting or customer-service-improvement ideals.
