While at the begining I thought I sensed a bigger argument here, the further I read I am certain the author either prefers to discount MITM or lacks the understanding of the full scope of a MITM. I agree that there are other evils of the web but that does not mean we make trade-offs.

The last paragraph goes as far as to say

"The ad is not from the website; rather, it is inserted into the datastream — after it has left the Web server as it streams the web page to your computer — by your own Internet Service Provider (Optimum in my case). This is called "watermarking", a variation on the classic Man-in-the-Middle attack. So far it's an infrequent occurrence and not a major problem, and in any case definitely not a security risk, just Yet Another Annoyance"

You let go of your user's privacy and security the moment you make such a trade-off calling it just another annoyance. While visiting this site a MITM could possibly inject a malicius javascript or sticky cookie. How is that just an annoyance? Protecting this is the biggest selling point of HTTPS.
