I kind of agree with their original thought, if the game can't succeed on one large platform then being portable is irrelevant. If it does succeed then porting is an additional cost but it's a cost you can weigh up and choose to do or not do, you have the choice. That seems like a better option than over encumbering yourself to begin with by adding in effect a bunch of additional cross platform requirements.
