I haven't read the article yet, but language is an organic thing, it evolves and changes and sometimes even dies out completely.
On a somewhat related note, my manager was not allowed to watch Sesame Street (she's 40 something, so this is a long time ago) because her parents said it was too American and would teach her incorrect things that weren't 'proper English'.
A bit silly to me as it's mostly just big fuzzy monsters frogs and pigs and things having fun with kids and learning to count in Spanish. A shame she missed out on it.
