In the hopes that it will help spread adoption of HTTPS, I wrote a web server that serves your sites over HTTPS by default, using Let's Encrypt: https://caddyserver.com - It also redirects HTTP -> HTTPS.[1] There's a lot of misinformation out there about certificates and HTTPS, but don't let it stop you from encrypting your site. Regardless of Google's move, there is no excuse for any site not to be served encrypted…
Honest question: are you willing to indemnify your users when the next Heartbleed-like attack comes out for the underlying SSL library you are using in your product?
If you are willing to do that, and will offer me a no-cost wildcard domain certificate, I will switch to your product and start using HTTPS.
