This kind of claim is often made (often by smut mongers), but I don't remember (though may have forgotten) ever seeing any examples that really back up the claim. Can you list some?
Let me try: Not just technologies, even religions have used sex to sell themselves. Take the kind of things that are sold (in terms of unsubstantiated guarantees of carnal pleasures in heaven after death if you follow the code of conduct proscribed by God(s) via his appointed messengers) you will see that a very large part of this promise is some kind of abundant sex (akin to unlimited download/upload). See for example this sales pitch. [1]
What I meant (and I think the parent of my post was talking about, though I could be wrong) is the old chestnut that the sex/adult industry innovated or popularized all kinds of technologies.
Edit: I can't see the main being that this "is about sex" but rather that this is about privacy and privacy is things people do that for a variety of reasons they don't want some people to know about. Certain sexual behaviors are included here but it seems far from funny or far from "bringing things down to earth", given that what happening is a variety of women suffering in a socially repressive nation.
There's a "liquid remix" video of the quote on YouTube https://www.youtube.com/watch?v=9tw_5OfFycU
There's a white-people "jazz" song named after it: https://www.youtube.com/watch?v=cEORdH7RzYw
Josh Woodward has done another rock/pop song probably referencing it: https://www.youtube.com/watch?v=hYptvK41Bi4&list=PLDZvNEf3nY...
