I wouldn't like to sound too harsh, but honestly, it seems like the author doesn't have any idea about what LaTeX can do, or what is it used for. Many of us would prefer LaTeX over HTML for almost any kind of document, without hesitation. It has many more functions both at lower and higher level, it's easily extendable (tired about \left( and \right)? Just define a \paren{} function! And that's just a tiny example), it has guaranteed support for certain characters (in HTML+CSS+Js, the browser can affect the font and possibly the encoding), etc., etc., etc. Well, yeah, it probably can't be used to create a web app, but, you know, most documents don't have the slightest need to behave like a web app.<p>It reminds me of the people who want to "fix email", without realizing that the only problem is that email doesn't cover certain use case that affects them, but it's fine for a lot of purposes.
