He is ecstatic because his app netted him $3/user with apple taking 30%. Now that his app is free he will make $.70/month/user.

Apple was taking 30% of his profits before but has given him a way to make more money per user long term.

@nika, the reason you should not be ecstatic is because while apple did help connect your customers to your product they did nothing to ensure that people continue to use and pay for your product. You did all that work and you should feel entitled to your money.
