fair. It seems 'opt-out' is fine to me though and here is why: I want to contribute to some persons tiny little 4-stars github project because it saved my ass.. it is a bit audacious for long-tail repos to be signing up to accept tips; but sometimes my long-tail tip will cross her long-tail repo.
Even more, what does mitsuhiko care if other people are getting money for contributions to his repos. If mitsuhiko is getting spam or seeing stuff in his issue queue despite opting out; that is a serious breach of ettiquite.
It doesn't seem to me this is the case though.. it's like he is angry that other people are getting emails?
