> Google support asked us to write a business case justifying how answering our support question benefited Google.

I have never had this experience with Google Cloud support (or support for any Google product -- free or paid), and couldn't even fathom what that kind of response would look like.

The only time I've ever seen anything remotely along these lines was when requesting a new feature for an enterprise product that we sold at the time (we were a channel partner), and even then, it was an online form that was asking about competitive information (e.g., "does anyone else on the market have this feature?").
