Apple does the same thing as Google, the button is only labeled "Get" for free apps, for paid apps it's labeled with the price.
Paid apps largely failed as a business model though (why would a consumer take a risk on buying a paid app that they can't try before they buy) so most apps that you pay for are free apps with IAP subscriptions... which I guess makes it a little more explicit that you're renting the app, for better or worse.
