If anyone demands I implement some feature into one of my open source projects that I either don't have time for or don't want to do, my response is one of the following:
- I'll get to it when I can (if I actually care to do it)
- You are welcome to implement it yourself and submit a PR
- You are welcome to fork the project and do it yourself or convince someone else to do it
But thankfully, my projects don't have a very wide audience, so requests/demands are rare.
Same. My turnaround time on that has gotten so quick, that I just don't meet people now. Can't talk too much to someone if you never meet them. And for people I already know, I just assume they're not interested in anything I have to say.
