Yes, and I find this argument quite tiresome (mainly due to its frequency) on English.SE - Google ngrams are really interesting, but it's not all I'm interested in. If something's a modern 'corruption' (by whoever considers it such) then all an ngram's going to show you is yes (or no) it has (resp. not) been corrupted.

Imagine if English (Language) teachers took the same stance. A+ everyone, if that's how you say it, you're correct, there is no wrong.

(And then is ESL different? Seems like racism is the effective conclusion!)
