Since you clearly quoted me, I wanted to clarify that I'm not saying anyone can just throw down a personal webpage with no learning involved.

I'm saying that it being open-source is only really meaningful when you want to self-host it, i.e. on your own server or that of a hosting provider of your choosing.
And then because self-hosting requires a certain technical expertise, that's when I'm saying that anyone wanting to self-host should just as well be able to grab some HTML template from the internet and host that instead.

So, these services do exist for a reason. I'm just questioning their usefulness for self-hosting.
