Come, come. If Spock was arguing that blue was blue, McCoy would have insisted it was black.

"A Piece of the Action" is a good example. A society contaminated by the presence of a book left behind by the Federation. Kirk does interfere with their society to a degree, but it's done as a means of undoing the damage that had already been done. By the Federation taking a 40% cut of their economy, the money can be redistributed back to them so they may create their own civil society and not one based on an Earth culture.
This is a great point. The Federation caused this problem, it's their job to clean it up and more than just saying sorry.
