Distributed authority is the “killer application” of  indie rpgs, not only makes playing and running games easier and more fun, but even the range of things you can do with rpgs is increased in a staggering degree.

Said that, I would not refuse to play a game with a “traditional” GM-centric authority (assumed that I am not the GM – way too much work for something that should be fun – and that I trust the GM). What I would refuse to play is a game with very confusing authorities, or that hand-wave the entire issue with the usual weak platitudes about “playing it together”.
