It’s 11:43pm on a Monday night. My 6-week-old son is asleep in my office so my wife can get some uninterrupted rest for the first half of the night. He’s finally asleep now, and I probably should be also after a full day of work. But I’m not done for the day. Even though I’m a software engineer by trade, I’m also a computer programmer by hobby and passion. So I do what I’ve been doing for well over a decade now: I boot up my computer to write some code.
OP wanted a fun child project, but it’s not fun anymore, just responsibilities.
The problem I see is just a difference between expectations and reality.
Expectations were: it would be fun to give people something for free, create open source, be part of some community. Maybe even get some recognition, maybe better job offers.
Reality is: noone cares about your open source project enough to pay for it.
And such is life. Noone stops you from just stopping working on it, and that’s an adult option. All open source licences have a clause like “I don’t own you nothing”, and maybe that’s the moment to use it.
