When we say "don't do X" we mean "the obvious way is wrong". If you have enough knowledge to ignore the advice, you likely are already aware of the problems with the obvious solution.
I'm pretty sure you can come up with scenarios where parsing the output of "ls" is indeed the simplest solution, but that kind of article is supposed to discourage people who don't know better from going "oh, I know, I'll just parse the output of ls". As a general advice, people should indeed be pointed towards "man find" or "man opendir 3".
