People who can't see use the same browsers as everyone else and they run JavaScript.

There is no reason for Javascript to be required on that page, it is static and should be nothing more than a simple HTML file with a few images, the font and a style sheet. It is slow on a decent desktop PC with a fiber connection, I can't imagine on an old smartphone. Recently featured on HN: https://danluu.com/slow-device/
But maybe we shouldn't blame the author too much, she is using Squarespace, that's the kind of service people use when they don't want to deal with these technical details. But Squarespace should know better and be ashamed of delivering such crap to their customers.
I use uMatrix to disable most Javascript by default, and enable sources one-by-one if necessary for a web app. There’s no need to use Javascript on a blog post, certainly not to dynamically load in HTML text and images, so I generally don’t even bother to enable it, and just hit the back button.
The way I look at it is, a web interaction is a conversation: my browser asks a server for a resource, and the server returns it. This makes sense for static HTML: ‘server, please send me this blog post’; ‘sure, here you go, and here are some images or fonts or whatever to make it prettier.’ This, OTOH, feels just wrong: ‘server, please send me this blog post’; ‘sure, here is this list of instructions for you to follow to assemble to blog post.’
Web apps are fine, Javascript is fine for that. Forcing the use of Javascript to do what HTML already can do natively is just wrong.

Seriously, it does have use in building web apps, but the vast, vast majority of web sites I encounter should be static, or progressively enhanced.
