Yes, the situation superficially resembles Cambridge Analytica, but there's a few differences here. People aren't building detailed dossiers of themselves on Google Drive like they were on Facebook, and Transmit is a client app that is honest, open and up-front about how it uses your data - to move it in and out of Google Drive.

To be clear, the problem with Cambridge Analytica was not Cambridge Analytica. The problem was - and still is - Facebook's habit of getting everyone to overshare and self-surveil. There needs to be some control and vetting over the apps that have access to your data but not so much that actually honest developers are quitting the game.

My guess is that Google just doesn't want third-party clients (you can't shove "AI" or "Investor Advertising" into it), so they're slowly turning up the heat by abusing the data scare.
