Let's Encrypt is 10 years old now

Hands down one of the greatest services out there, stopped a racket and made the internet secure.

I remember a time when having an HTTPS connection was for "serious" projects only because the cost of the certificate was much higher than the domain. You go commando and if it sticks then you purchase a certificate for a 100 bucks or something.

There's still enough people out there who don't know better, manually (or auto-renew) purchasing new a certificate every year from their hosting provider like it's 2013.

AFAIK there's things like Extended Validation Certificate Verification that used to make the browser address bar look more trustworthy by making it green but I don't know if its still a thing. At least in Safari, I don't see a green padlock anywhere.

Huh? EV certificates are actually certifying you're the (juristical) person you're claiming to be based on ID and trade register checks, unlike Let's Encrypt certificates which only certify you're in possession of a domain. Isn't using EV certificates legally required for e-commerce web sites at least in parts of the world, and also obligatory for rolling out as MasterCard/Visa merchant by their anti-fraud requirements along with vulnerability checks and CI/site update processes being in place?
