And one in ten will respond, "I already bought this one; why are you being actively hostile to me?" The other nine will route around the problem, whether by leaving Linux or by taking a solution which the FSF has decided is haram. All ten will be more likely to ignore what you say in the future, when they ask for help. "Which is the way he wants it. Well, he gets it. And I don't like it any more than you men."
"Help" that merely says "you made the wrong choice" is barely any help at all. "Help" that says "this is the choice you should have made" may be better, but isn't likely to be appreciated any more. Help that says "You made a choice that we don't have free support for yet, but here's what to do in the meantime," is much more likely to do The Right Thing in the long run. Especially if "what to do in the meantime" includes how to help change the situation. It says we're working on the problem (including you, now that you're with us), rather than suggesting that the problem will not be solved.
