Unfortunately, what you describe is the ideal case.

A typical case might be:

1. Developer releases free app

2. Users find it useful

3. Developer seeks to monetize, adds some mobile ad network libraries

4. Ad network libraries want the user's location

5. User's who liked the app now find themselves OK'ing a frivolous-seeming permission during an update, or they have to uninstall the app, potentially losing access to some of their own data.

And so we find our developer on the slippery slope. Putting the power to cause those apps to fail when they do dubious things in the user's hands means that developers would be more discriminating about their monetization partners, among other benefits.

All good points and I'm sure many of the app developers on HN will be able to give reasons as to why they are unable to provide this information on the apps they develop and I suspect it is all closely controlled by the platform as opposed to the developers themselves.

If the app I downloaded said "Our free version requires your location due to our arrangement with our Ad providers" I would have at least known why they were wanting my location.

I know this doesn't solve the problem, people will still have the choice to either accept it (albeit grudgingly) or uninstall the app. What it does do however is acknowledge they are asking for permissions to a users data. If someone asks for my permission to use my car is it unreasonable for me to know why they want it?

If the permission to get the user's location always bugged the user and most users said "no" the ad network library would quickly realize they're losing money by asking and stop asking.

In Android's case there is no way for them to know. The app either has the permission or it's not installed.

In iOS they do know. The user can give permission, not give permission, or can give it and revoke it later. Their analytics can then tell them what percentage of users are not giving them that info.

In any case, you as a developer could also choose to speak up and say to the network ad provider. "I'm choosing a provider that doesn't need more permissions".
