I want free things.
How about "I wouldn't pay a damn thing for it"
I wouldn't want it to be a purchase option at all. What the heck.

What I don't like paying for is features that are already sitting there and gated simply to milk cash. Examples are F2P milk-shop games where you can buy 500% XP boosts to make leveling actually possible, etc. It doesn't take develop time to make your character level faster, it's strictly an engineered cost to force money out of you.
Asking me "Hey, wanna pay extra to include new features of interest to you?" is a totally different story IMO. I'd rather vote with my dollar than just have to accept whatever the developers put on my plate as they try to 'guess' the best solution to please the most people.
