I would actually like to see a source for this claim. Google did state that it would stop scanning emails for targeting ads "later this year" at some point in time. But I haven't seen a document after that reaffirming that this has been done.

I suspect GDPR would have been sufficient threat since not all people involved in a scanned email were guaranteed to be Gmail users, so gaining consent would have been problematic.
