Google Takeout predates GDPR by several years. I'm not sure if there was any other legislation in place in 2011 that required Google to provide something like this. My recollection is that it was not directly related to any actual legislation at the time.

That is a good point of correction. It looks like Google's Data Liberation Front was formed (at least in part) in order to abide by government regulations, certifications, and procure more business (https://fcw.com/2010/09/google-apps-government-reach-grows/2...), but not at the behest of the EU. It looks like Gmail was added to Takeout in 2013: https://en.wikipedia.org/wiki/Google_Data_Liberation_Front
