It changes your relationship. If they get it for free there's a hard limit on what they can expect from you. The second they pay $0.01 for it they'll expect customer service. Maybe you can find out who your product's best users are and ask them what new features they'd pay for. That way if nobody likes it enough to spend money you can just leave it the way it is, and if you start charging it's for new features that your best customers love.
