That guy is not asking, is demanding. I use lots of open source software and am aware that the developer is often stretched thin. If I can’t help with the project (can’t say I have in the past two decades) I want them focused on what is important and what probably keeps them motivated, writing code and adding cool features. If they have time, fix bugs. If there is more bandwidth, write documentation.

Not wasting time making an executable for every OS out there because some ingrateful asshole is too lazy to figure out how to read instructions in plain English.
