Apps market is completely full. There is much more offer than demand/need. Once "supports" are broken, in this case, when people get used not to pay, to make them pay again, something must change (offer, demand, rules). I'm an architect (real architect , not IT) and in this market it happens the same, people are not paying anymore for ideas, they only pay for project drawings. The competition (offer) is too high, if you don't do it somebody will.
