Tell me you don't understand the difficulty of maintaining a really useful and complex free tool without...you know.
All the writer has done here is screamed their ignorance (which, to be fair, is not at all simple) of the complexities of using free/open source and also maintaining something huge and complex WITHOUT being huge jerks about it.
I do wish there was a simpler way to essentially do two tiers of "service" -- but for now, "you either 'pay' in terms of digging in and learning or you 'pay' with real money" seems pretty reasonable.
