It’s not simple criticism though is it mate? It’s criticising people who are contributing to the world while offering nothing yourself. That’s the whole point which has already been pretty clearly explained.
If we take it back to your original comment you’re literally criticising the amount of free work someone chooses to do. I’d hoped you might see the analogy but it seems like we’re past that point so let’s call it a day.
Good luck though mate, maybe think about it a bit more when you don’t feel like it’s a battle with an anonymous Internet person and can look more objectively at the points made :) x
