You don't see how the economics of startups interact with the open source ecosystem and how someone's view of that interaction might affect their choice to not make something open source?
I can certainly see how they might be related, but the answer doesn't clarify how---rather it seems completely disconnected in the first and second halves, which is why I'm wondering if it's just an editing error.
Just poor writing. I've talked more about this on my blog. Open source usually only works for tools for hackers. I want to reach the rest of humanity.
