It doesn’t matter, why the present is garbage, it’s garbage and we should address that. Statements like this are the engineering equivalent of “it is what it is shrug emoji”.
I don't think your opinion is grounded on reality. The "it is what it is" actually reflects the facts that there is no way to fix the issue in backwards-compatible ways, and it's unrealistic to believe that vulnerable frameworks/websites/webservices can be updated in a moment's notice, or even at all. This fact is mentioned in the article. Those which can be updated already moved onto a proper authentication scheme. Those who didn't have to continue to work after users upgrade their browser.
Fans of a programming language stating they like the programming language is hardly thought-provoking stuff. There are also apps written in brainfuck and that means nothing as well.
