Ask HN: Looking for quote on technology being used for revolution and porn

Hi, I'm looking for a quote I read years ago that, paraphrased, said something along the lines of: You know your service is successful when it's being used by freedom fighters and pornographers.<p>Realise it might be a bit vague, but I think it was a fairly well known quote and I figured if anyone knew the source it would likely be someone at HackerNews.<p>Cheers.
