For me it's not that it's confusing, it's annoying to read because it indicates that the programmer didn't actually take the time to learn the language, and is instead writing it as C/PHP something else where expressions in if statements don't need to be explicitly boolean (the examples in the article are Java). If they wrote that, what else do they not understand about the language?

What if it is 0 but not null? I write in a few different languages throughout a typical week. It is nice to have some explicit statements when juggling between them. I know them very well, but it is still tricky when going back and forth.

That also wouldn't even compile. I also write in multiple languages, and for languages for which this is an issue I use a linter. This isn't even an issue in C if you compile everything with the appropriate flags (-Wall or -Wparentheses).
