I don't care if there is some exception at play here, that 5% of you actually do purchase after "demo'ing" the game - you're way in the minority.
It's a completely BS, and frankly idiotic, argument to make.
It's ironic that you are saying it's an "idiotic argument to make" when you are using the smallest slice of anecdotal evidence (yourself) to extrapolate that everyone else must do things exactly the same. Unless you follow every single pirate's habits and spy on everything each one does, the only BS argument here is yours, since you are just pulling shit out of your ass. Sorry.
