Can't read the article because the captcha won't load, but this reply doesn't make any sense. What can the browsers do without the cooperation of the server? You don't really need encryption to deal with that specific problem, but you do need signatures, which means you need a certificate anyway. It's quite a strange attitude toward the problem.

The captcha is because you come with a Referer of news.ycombinator.com. Try opening the website in Private Mode.

There is no captcha. It's a fake page meant to harass certain referrers.
