On the flip side there is no one holding a gun to anyone’s head to either be a customer or be a dev. Isn’t that the beauty of competition?In Italy we say "è come chiedere all'oste se il vino è buono" (which translates to "that's like asking the innkeeper if the wine is good"). They're the innkeeper, of course they would think they deserve a cut, and possibly even a bigger one if they could get away with it.
