1. Logs are not free. Stackdriver was not an option back then.

2. If the phone company charges me extra they tell me which numbers I called. Here a cache miss started happening. Only in production with no tooling available (at the time) to determine why this was happening. A single number of "data read" was all the information given. Not even the table name... That means you end up looking for a needle in a haystack.

I'm guessing you work for Google because your attitude seems similar. No they don't *have* to provide that service which is exactly why they suck. A service oriented company would make the *effort* to provide a user with this information. Especially a paying user at gold level.
