No. Apple makes money from subscriptions, and Apple controls the app store with an iron fist. In a hypothetical world where the price of apps falls to ~free, Apple will just ban free apps in order to recoup that revenue. Hell, if you think that you can build apps for free, then you need to explain why Apple wouldn't do the same themselves, charge users a recurring fee for the privelige of using them, and then muscle out any competitors using their natural monopoly to reap the profits for themselves. Apple doesn't work for your benefit; like every other paperclip maximizer, they have a sociopathic focus on profit at all costs.
