Maybe. Google doesn't specify how they are fitting their data in their training program. But to be clear, I didn't say they were just for development purpose. I was imagining that'd be their interpretation. They would see that as telemetry or diagnostic information.

But if they will provide an opt-out option, that will help resolve the issue. EFF isn't wrong, they are catching an implicit fineprint, and Google is interpreting that very differently (not being Google).
