Well, yes and no. It might very well be that what TSR paid was, in fact, the fair market value for the rights to make a Buck Rogers RPG (though I doubt we'll ever know for certain).The devil is in the details: specifically how much TSR paid Williams' family for the rights to a Buck Rogers game.
Rather, to my mind the issue is one of the appearance of impropriety, which is a separate consideration from impropriety itself. If you're the VP of a corporation, and you're in charge of throwing a party for an outgoing CEO, you don't employ your wife's catering company, regardless of how good they are or what you pay for their services.
