This was one of the less obvious uses of sarcasm in recent memory.

It's entirely possible I'm wrong, but I'm hinging my decision largely on the location (hn, where invasive user tracking is synonymous with evil with nearly everyone) and the "sigh".

I don't think so... If it was sarcastic, it wouldn't really be worth mentioning, like saying <sarcasm>Oh great. Another car with airbags!</sarcasm>

Good point, people never post useless comments.
