I'm surprised no one asked if it even matters, as even the dumbest webmaster will always promote sponsors that make them the most money?
Does it really matter if the sponsor "shaves" 20% or if you lose 20% of sales because they are incompetent idiots with buggy or poorly optimized tours?
Obviously it's best to work with only "honest" sponsors, but if "shaving" sponsor turns out to make more money for you, it would be pretty hard for anyone to turn down the extra $$?
