You just gave another false dichotomy. Just because a corporation looks to use BSD licensing doesn't mean it won't contribute back. You're attempting to derive intent from a license choice. It's not that simple.
No, I didn't. Notice how I used words like "might", implying that the scenario I described is but one of many plausible scenarios.
Certainly corporations contribute code to BSD-licensed projects. But equally certain is the fact that some corporations contribute code to GPL-licensed projects when they otherwise would have kept their code to themselves if they weren't legally compelled to open it.
