I'm not saying that there aren't marketers who want to keep their campaign tactics secret from that kind of review, but if they exist I've never met them. It's always been G&FB making the case for "advertiser privacy" which publishers mostly see as a running joke.

It's probably just a coincidence that every effort made to protect advertiser privacy happens to also make auditing the system or optimising it outside of the platform harder.
