you come pretty close to invoking godwin's law, here.

if you depend on a place for compensation, then you should be interested in its' success, and if some bonehead (let's not pick on marketing, since it's not always them) has a stupid idea, and money is being wasted on you doing that, it's actually your responsibility to do something about it.

per the law of supply and demand, it's also completely reasonable to leave them behind. a lot of companies with good ideas fail because they can't retain talent enough to get any cogent work completed.
