Sorry, but that statement is completely false. I suggest you re-read the entire history of the situation first before posting that kind of stuff....& you obviously don't understand what Open Source is, what it offers, what it represents, how it works or what it stands for.
I wasn't clear what I meant perhaps. I agree there is no way p2pool (or bitcoin) would work on a closed source basis. It has to be open for large number of reasons.
My 'problem' with open source for p2pool, for want of a better word, is that developers cannot enforce users of the software to pay for the development effort. So free as in speech and not free as in beer. While lots and lots of opensource projects are done for the love of the craft I'm not sure how that would work for something like p2pool.
I guess you could say the same about Bitcoin as a whole. But there are ways for developers supporting the bitcoin network to get paid something for their effort.
I wonder how much that is if you weight it by the bitcoin price at the time it was donated. Either way it's maybe not enough to expect someone with the necessary skill to put in the amount of effort required.
