Right, but that's more a lack of reward than outright punishment. If you work with these people on something that "crosses boundaries" and that something succeeds, you can credit them and in the hope to help their career. I agree that larger places are worse in this regard (though there can be a small part of a large place which is, well, small enough to work like a small one), and that you should generally make sure you're rewarded for your work, and if you're not, either work less or work elsewhere.
