Maybe just place a glass crystal dome over them all and all disgruntled musicians take a group fart in their general direction

You are not the first to have grievance toward that sound designer as there's people that own the Microwave 1 in which is dependent on large external memory card to place one's new sounds on or import new waves and sounds in that machine and will just say it's outright highway robbery what is charged for them with a damn disclaimer that they are his sounds and cannot be utilized in commercial realm nor sold in any way or form.
I say just make your own sounds because it's by very nature of trial and error and using one's ears, a person becomes a synthesis or better yet synthesis.
Do not mean to be 'snarky', but Tweakhead's words are very wise in making one's own trademark sound rather than continuing the 'cookie cutter' syndrome.
