The original comment of mine that started this thread:
Why isn't there a public open-source fund [...]
I know it doesn't exist. The non-existence thereof was what prompted that question. I have no idea what point you're attempting to make.
Clearly you are smart enough to realise what point I was trying to make, although it was perhaps tangential to your original question.
I do apologise for replying to you. If only HN would have a feature to block me from replying to you in the future.
So, the answer is that nothing exist.
Out of the given options a few also don't qualify (like I mentioned, Apache for sure, opensource.org most likely) because they don't spend money on software development at all.
