Your assumption that the audience for Cloudflare's post is "tech-savvy people" is accurate but your follow-up assumption that the websites that these tech-savvy people make are "most likely" for tech-savvy people is obviously incorrect. The website I built for music. Certainly, my users need not be tech savvy to use my site. So if I installed this popup, there is a good chance of showing it to some non-tech people. I would assume that a lot of people that read HN have built products for non-tech people.
