Not limited to software but modern society has a REALLY serious entitlement problem. (To the point where if I see a video on Reddit of someone screaming at a retail employee, it is not even surprising anymore.)
I’ve had free and open projects for years, with evidence of thousands of users. Yet I could count on one hand the number of times anyone has bothered to thank me, much less donate. I do occasionally get E-mail requests for support but sadly at least half of them have had a complaining/entitled tone as if I am not doing every last bit of this for free. I have had zero offers to help with development, documentation, or really anything else. And interestingly, some of those E-mails have come from some pretty well-known large entities, be they government departments or large companies — organizations that should have more than enough resources to give a damn.
Sadly, it is not better in the for-pay universe. After publishing apps, I have found that essentially no one will outright “pay once” for something anymore, no matter how cheap (leaving things at the insultingly-low price of $0.99 for weeks does nothing). Similarly, people usually will not contribute even a rating to help you out, much less a review. The E-mail/web info links on the store have never been used by anyone to reach me. And App Stores make it impossible to know who your customers even are, otherwise. So a silent relationship is maintained, where random unknown people update their apps over time, continuing to benefit and all I can assume is that they are still happy or something.
So my conclusion after decades is this: you do the projects you like to do for your own benefit, and no one else’s. They are résumé builders so you have something to show when looking for a corporate job that actually pays. If anyone doesn’t like what you’ve built, you are 1000% allowed to ignore them. If someone happens to appreciate it, that is a bonus but not a certainty. And you must be prepared to receive no money at all from these projects, much less enough to live on.
