But it was the right thing to do. The fact that encryption wasn't built into the web from the beginning was, in our mind, a bug. Today, almost exactly four years later, the web is nearly 80% encrypted thanks to leadership from great projects like Let's Encrypt, the browser teams at Google, Apple, Microsoft, and Mozilla, and the fact that more and more hosting and SaaS providers have built in support for HTTPS at no cost. I'm proud of the fact that we were a leader in helping start that trend.
