It's been interesting to watch the web landscape change over the last 8 years. Back in 205 when I joined Google's Web DevRel team, I worked with Chrome security engineers to create a persuasion article [1] about why all sites should be encrypted with HTTPS. The fact that they felt the need to create that page at all indicates that HTTPS was not that common. In 8 years the ecosystem has got to a place where HTTPS is so common that we don't even need UI for it anymore.
