I don't like to be told that information about a project should be disclosed to developers on a "need to know" basis.

You know the sort of thing: "Oh, the developers don't need to know about the business goals of the project. That's only relevant to the business analyst."

Or: "Oh, we don't need to explain the end-to-end workflow to the team, just as they know their inputs and outputs."

Bulls**t! I've always found that kind of knowledge invaluable...
