I'm going to get skewered alive for saying this, and I do believe their intentions were noble, but I honestly think Let's Encrypt has done a lot more harm than good.
It's completely deflated the opposition to the CA racket, but not given a comprehensive alternative.
There are servers that can't run certbot for a variety of reasons (including administrator policies that people running the webservers can't control.) The 90-day expiration is the most arduous of any CAs out there by far. Not only are there no wildcards, but there are strict limits on the number of subdomains you can register per week.
And if you don't like it ... too bad. There are zero free alternatives.
Most of us are hackers and can work around these limitations, but not everyone can. You can't expect most people to set up certbot, let alone write their own version. You can't expect them to build some system that automatically batches and registers new subdomains and maintains all those certificates.

That's a lot of it as well. I'd go so far as to say the majority of internet sites out there (by number, not by traffic volume) are little commodity hosting firms that give you a web GUI version of an FTP client, and maybe if you're lucky charge you $10-20 a month for SSL as a checkbox feature in the payment options.

It will probably just look for <input type=password> and if that exists, show the "Not Secure" message.
