Markets for targeted SaaS solutions exists. Nobody is going to develop these for free and the businesses who need them are more than willing to pay (the value gained is much, much higher than the subscription fee). There are enough different businesses with the same need, that economically combined (through fees) they can support a team that develops the necessary software. These businesses are not going to collaborate with their competitors to develop the same software in a million years, but through SaaS providers, they basically do. Most of the people I know who work in software are basically involved in this at some level. It's not going away, and in many cases, it is really the only reasonable model.
