You’re getting financial benefit from my donated effort. I don’t mind - I wouldn’t opensource my work if this bothered me enough. But GitHub issues opened by leeches have a certain entitled tang to them - “Hey could you donate more of your time so I can make more profit? I won’t pay you. Maybe you should be thanking me for finding problems in your work and pointing them out to you. Get to it!”
The reason you don’t contribute doesn’t matter. You’re profiting from my volunteer work and asking me to volunteer more so you can profit more.
Justify leeching to yourself how you like. But you won’t get respect from me until you contribute back.
And, yes, if you work at an immoral company, that is also absolutely on your hands.
