It's a tough position other companies are placing on SO. On one hand you can't alienate a portion of your community by closing all API/programming questions which are of a more proprietary nature just because they're of a proprietary nature. On the other hand, the general trend these companies are starting, to not build out a real support channel, is indicative of developers who don't really understand sales channels which should not be SO's problem. I wish more start ups would get better guidance about support if their products are aimed at developers. Really, they're missing another channel of communication and new business discovery.
