While it sucks to not be able to work on it full time any more, it boggles my mind that it'd be possible to earn enough from a tool like that to work on it full time for any amount of time in the first place. Not meant as a criticism of you - in fact if you've managed to do that, hats off, clearly you must have done something right with it.
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.
