Maybe you should read the article, especially the section on historical usage. Saying ‘less’ was never wrong, there was just a bunch of fancy academics that came along once and said it’s wrong, while everyone else just carried on as usual.
Annoys me that “less” is always correct, which makes “fewer” completely redundant, and yet it’s a short word that could be valuable in conversation if opened up and reused for something everyday that has a long name.
