What kind of mentality is this? I remember before snapple was a widely known name they used to give out free bottles all over Los Angeles. I never thought to myself, I better not taste this free drink until I know the actual price.
They are specifically hoping you'll become dependent on it and then feel compelled to pay. This shit works because people like you believe it doesn't.
Because they haven't decided the price yet, or because they don't think the feature is mature enough to justify charging for?
Though even if they really have the motivations you describe, that's fine too. There's a chance this is such a valuable feature you could feel compelled to pay any price for it, but you get to try it for free? That's purely to your benefit: it's not heroin and you won't really lose by trying it and then it being taken away.
