You're getting voted down (likely for only saying the article is wrong but not why), but I'm curious your reasoning. I've tended to write in POSIX sh (for maximum compatibility - and because it was just the way I learned) - but am happy to use bash too when the project allows and it makes sense so not sure I get the hard line stance. Wondering what I might be missing to evoke such a response.
