Earlier quoted context omitted.
The number of people who use whatsapp is an order of magnitude or more than the number of people who consciously use Google drive, as in people who know google drive exists. Even the people who have google drive, most of them have much less intimate data on it than in their private messages on WhatsApp. If we are to take the position that all users are tech literate and should be fully in charge of how their data is…
And you are still avoiding the equivalence that everything you describe is already happening with sms messages at least, and generally much more. None of your arguments carry any weight especially since they don’t explain why it’s ok for data to be unencrypted on your google drive in the first place.
SMS had the same problems forever, but isn't owned by a company, thus you can't blame xyz company if random apps access your SMS. No company got ever investigated by multiple nation states over that.
You still haven't addressed my main question though, how will a random app scraping your WhatsApp be any less of a scandal than Cambridge Analytica?
