I don't know. I've worked for a couple of companies who open source their software and they don't open source because they believe it's good for the world (they may or may not, but it isn't the driving motivation), they open source because it's a near requirement for building a profitable business. It's easier for a no-name company to convince enterprise clients to use your software when the code is open source - it's often a non-starter if your code is closed-source. It's easier to get developers and keep them happy. It's easier to get community contributions. It's easier to get your name out there (you lose a LOT if you have a software product without a GitHub).

As long as open-source is a near requirement for getting traction, I don't think there is much to worry about.
