wohhhh, that's pretty hostile don't you think?
I've being reading through this whole debacal myself, and I haven't seen any good reasons so far.
I think tip4commit is a pretty hostile project itself. It deserves a hostile reprimand. And since the creator refuses to even opt-out (let alone opt-in) projects, I really can't feel sorry for them.
Why is it a bad idea?
Maybe people have already stated the reasons. And you (wrongly) think you have effectively refuted them. You are being, to choose a mild word, dense.
Sometimes it's best to just look at how mad you are making people, and draw your conclusions from that.
You are making something people don't want.
