I was satisfied with the answer I got: "well, our bosses dont really know we're doing this."

That could be where the latest change came from.

I was working at a company to Open Source a particular product of theirs and it got killed from upper management after some rather nasty political stuff went down. I later found docs on why it wasn't to be Open Sourced. Mainly due to much of the code having different styles. (Because most of the code had been Open in the first place.)
Was I bitter about this? yes.
Was I upset that it got killed due to someone elses misconceptions or bias? yes.
Did I realize it was totally out of my control and that it was better to just let it go? yes

dep Unless you can bring legal bearing on them, it's better to chalk it up to experience. Have the client sign a contract, etc... to make sure your code isn't abused. You can write a letter to Music City expressing your displeasure and it may help you get some stuff off your chest, but don't count on any change. It may happen, but don't count on it.
