obviously YOU would prefer that because you are the receiver but the owners would hate it because now they would have to "spend money" whereas before it didn't cost them anything at all. you see when you create a token out of thin air, it doesn't cost you anything since you get the whole 100% of them for free. so paying in those tokens that you created for free is preferable to the token owners which is why they do it in first place. but paying in something else like bitcoin means they have to go spend money and buy bitcoin to be able to pay and that costs so they never do it.
