I’m not writing code for free! No, I won’t help by sending crash reports for your FOSS program! No, I don’t want to help debug your binary!
Look, I appreciate the people who give everything they can to helping others by writing code that is Free as in Free Beer. Alright, thanks for letting me execute your software how my system prefers, like Free as in Free Freedom. Super, you let me even do as I please by redistrubuting, Free as in Free Speech.
COME ON NOW!
Free softwares developers should be, like a true renaissance man, doing the work with no expectations in return. If you code good, maybe I would be obliged to help out. Maybe I’ll donate to your project, or maybe I’ll buy your merchandise, or maybe I’ll go to your Linux-themed event.
Other than that, let’s keep it professional.
You write your code pro bono. Or else, it won’t get used. Otherwise, follow corporate.
