There always have been, and continue to be, people making perfectly good money from this sort of software. I'm not sure why you're surprised, given that people make profitable fart apps for phones, and that it is apparently rational to bury people with money to run any number of fundamentally useless startups.

While we are at it, any advice of how to market such software? I mean, when there is more or less saturated market.

Thanks!
