I try and remind myself there will always be competitors selling the same thing cheap enough to put you both out of business. You have your users AND they are paying. How sustainable is a business where he absorbs all the costs and doesn't bring any revenue in? How much support can he continue provide to free users? Especially if they get into the large numbers. You are treating it like a business, he is treating it like a project that he can drop at any time. In my eyes, he is collecting your future customers for you. When he spends to the bottom of his pockets and folds, his customers will have to choose between your service or no service. Hold on, keep focused on your lovely customers. Give them amazing service. Go above and beyond for them. Stir up a little press of your own (make your stake on first to market a little early) Don't get caught up in looking over your shoulder.
