It doesn't matter in practice (and in fact there's some decent arguments that one is better than two or more: consider the current ford Go-Bikes in SF. Would it be better or worse if there were 2 or 3 mutually incompatible bike racks? You end up fragmenting your transit system). You can only offer so many rack locations, so if Lyft takes 2/3 of them, no other provider can be as effective anyway. If we were looking at another kind of public transit, say, subway trains or busses that were subcontracted out to private companies, would you expect 2 competing subway providers? Or two competing bus systems in the same city? I wouldn't.
