I disagree with his disagreement. I'm not able to overthrow my government to make it illegal for my only ISP to stop intercepting my traffic. HTTPS simply makes it impossible for my ISP to add stuff to the page in transit.

What's the gripe with Let's Encrypt? Certificate transparency?

Some of his arguments are wrong, some are not even wrong, some are absurd. Plus he seems to be an asshole. Being an asshole and wrong at the same time is not a great combination.
