Not sure on the agreeing part, as his post gathered more thanks than either your original one or your answer to his (for whatever worth this metric is).
Not sure on the direct attack either, he was "freely expressing his thoughts of the proposal", just from the developper side:

• "people working on their free time do work on whatever they fancy (regardless on what they should do, or what is usefull for other people)"

followed by

• "But you can try to convince them to fancy working on the same thing"

This is clearly not wrong, neither OT. Although I really find Smoku's communication skills abysmal, your reaction also seemed out of the line for me.

ps: I don't mean to be aggressive or anything, just saying that not everyone agrees on smoku's full responsability on this.
