What? I don't understand how you even came up with this idea, much less consider it so obvious to condescend about it. Do you have even a single example of a research project that got scooped because the Google Docs team forwarded their private documents to someone?

Lol. That's not what I said nor what TFA is claiming. The claim is that private data is used for training.

Google docs exists as a competitor to microsoft office. Google gives it away free to consumers for the same reason AI labs sell subscriptions for 10% of the price of the api. They hope businesses will switch to what employees know how to use.
