Getting paid for a product you have to put time and effort on? What a dumb thing. Amirite? People wanting art for free is a serious problem for creative jobs, you might think it's innocent but you are part of a rather extensive web of artist abuse.
Okay shall I make my mod paid then and watch people moan like hell ? As a fellow art producer as in I play music. I completely understand. If you asked to me play a gig for charity would I get completely triggered ? No. I would say yes or no depending.
I have always been in favor of mod makers getting compensated for their work so no idea why you are making that argument. Also you aren't a charity, you are asking people to work for peanuts for you.
