> I come from the camp who believed that open source is super beneficial and a positive movement
As do I. I've been very active in OSS for many years, because of the clear (to me) positive benefits it has for everyone. That's why it was hard and painful to retreat from it. I felt (and still feel) that my hand was forced.
> why is the open source community not furious with this situation
I'm not sure, but I do know that the OSS community has changed from what it used to be. Perhaps there's not as much of a unified mission or purpose as with the fine arts communities? Perhaps (and I slightly lean this direction) the OSS community has different ideals now that are more compatible with this? Perhaps it's a sense of resignation?
I don't know. It's an interesting question.
I do know that there are quite a few OSS folk who are, in fact, furious. It's just not an obvious majority of them, and most of the upset ones I've talked with have a sense that there's nothing they can do about it without withdrawing like I have. Their calculation is that it's still a net good to continue even with this problem.
