It has always puzzled me that even sophisticated audiences like HN regard this situation by killing the messenger. Usually reactions are mostly "meh", "Where is your tinfoil hat?", or "the US does it too".
At the end of the day, as proprietors of Internet services, the information being stolen from you or your company is your customer's data. You should care and be alarmed.
I'd just keep track of the usernames who say that, wait until they reveal their identity elsewhere on HN via a "Show HN" or something, then ask them publicly to explain what their stance is on protecting their users' data. When they give the famous cookie-cutter response of, "Obviously we care." then you can hit them with, "but did you not say 'meh' when this same issue came up a few months ago?"
