Wouldn't it be nice if there was an encryption system for SSL setup by W3? SSL does three things. First, it provides encryption. Secondly, it minimizes the chance of some falsely claiming to be your site. And third, a paid SSL certificate can confirm the owner and site's credibility at a level chosen by the buyer. The encryption part should be universally offered. Free SSL providers believe in that, but this is something that should be standardized and offered freely across the world wide web. I suspect this hasn't been done yet, because there's money in selling SSL certificates.
I also predict that if money is the issue, Google Chrome or Google, will one day show preference to paid SSL certificates over Let's Encrypt using a ploy such as "security concerns."
That sounds similar to all that happened with Google and co.cc domains a few years ago, but hopefully this doesn't ever happen. Let's Encrypt is a pretty great thing. It's never been easier to get SSL for your websites. I can literally attach Let's Encrypt SSL to a domain in a matter of 1-2 clicks in my cPanel.
Actually I have had issues over free SSL certificates in the past which led me just to buy one, especially with the Chrome browser. I agree that soon browsers may be turning preference over to paid certificates which is unfair
You can easily purchase and have your host install the SSL for you. Most hosts should install it for you for free. SSL is a requirement now days as you get bad google ratings for not having it.
SSL can be free and paid. LetsEncrypt introduced free SSL certs.
