So I only read the abstract, but the question is if the data is leaked, by accident, or if it's deliberately provided. My guess is that we're talking about the first scenario, and that this is an accident.

If that's the case, then I'm not surprised at all. Actually I also wouldn't be surprised if they sold the data, but that's a different story. If we look at OpenAI for instance, they have on multiple occasion shown that they do not have the operational experience or resources to run their services in a safe and secure manor, nor do they frankly have an impressive up reliability (in terms of operational stability).

I'd support your guess that all of this is rushed in an attempt to push for profitabilitet/growth.
