The author is talking about the web and calls it the internet. I see this often, but the internet is more than port 80 and 443. I get it, when normal people do this, but if you work in tech or are savy enough, i think that distinct difference is very important because it describes 2 totally different things. It's a misleading title, i wouldn't have clicked if the topic would habe been: the web - instead i assumed it's about "the internet" and it wasn't. Hmm. This will haunt me forever i guess.
