To your other point, we have in the past seen the media reporting these types of things in incomplete ways for fear of irritating their sources and losing reporting access.
If its true. In contemporary journalism the truth doesn't matter. Things can have perfectly reasonable explanations and be working as intended, and the only thing required to turn them into scandal is to omit those explanations and add a clickbait headline instead.
There's plenty of examples for that in Europe in the way journalists paint perfectly reasonable EU directives as utter nonsense handed down by stupid bureaucrats.
I doubt any company in America can tell you exactly what an app cost them to build. They can tell you what the product cost to develop, but the app itself is kind of beside the point: you don't get an app without the up-front work of determining the requirements, so why bother to separate the costs? Some projects have complex requirements and simple implementations, others have simple requirements and very complex implementations. The project cost is what everyone is concerned with anyway; and while the project manager should have the line-item information for the project, it's often not rolled up higher than that because the reconciliation would be nearly impossible.
