Corporate Open Source is doing perfectly fine. For over 30 years corporations have exploited the idea (ideology) of open source for their needs. With the cloud this has just become more visible.

Projects have already changed hands in the past and the licenses were changed afterwards. Now they ask the seller to change the license upfront to put that problem on the seller’s table. That’s the only thing that has changed, besides the fact that the old idea of "the software is for free but you have to pay for support" is completely dead in the cloud.

So, everybody open source developer until their project becomes relevant and promises a payday.
