This is more or less completely false. English has an unusually high number of loan words from French (on the order of 10k or so, I think), and this has made the language less Germanic than its historical origins would suggest. But English existed before Norman French arrived in the British Isles, and is still at heart a Germanic language.

Did you actually think I wanted fr-GB to replace en-GB?

It was a joke based on the Norman French references from https://en.wikipedia.org/wiki/Middle_English
