I'd love to see similar graphs for TLS.
Edit: Google shows it only for Chromium sampling but it's nearly 90% in most countries which is almost double what it was before the Snowden leaks: https://transparencyreport.google.com/https/overview
As much as I'd like to think people were concerned about the privacy of their communications... I don't think most of the masses actually care about security or avoid conveniences based on threats to their privacy...
I don't think "the masses" fall into the equation at all and likely haven't even really noticed the change besides the "This site isn't safe" warnings that occasionally pop up.
SSL helps against the skript kiddie at your local Starbucks, not against the NSA.
(Of course, not being able to monitor and log all web traffic all the time must be a slight inconvenience, especially after the TLS 1.3 SAN changes. But we still shouldn't fool ourselves that just because we can't break it, the NSA can't either.)
But every connection you're intercepting, you're providing airtight evidence that a misissuance occured (the certificate). It's only a matter of time until you're caught. With certificate transparency, it's broadcast to everyone in the world.
So yes, nation states can bypass pki pretty easily, but it's only feasible for targeted attacks. That's better than the status quo of dragnet surveillance.
In a way they do...
Every UPnP device is also a HTTP server (listening for SOAP requests), as are many other IoT devices.
I have two light bulbs in my room that are both running HTTP servers.
“The masses” are definitely deploying this type of HTTP server frequently
for the dot coms, let's not forget about Google's rank incentive.

Not to mention their lost access to private Google (and probably Yahoo, Microsoft, etc) networks and a myriad of other security improvements across countless software platforms.
Still a long way to go.
