When I search the Play Store for Geometry Dash, and click the lil button that says "$1.99," I get this page. It sure as shit looks like what I'm about to buy is Geometry Dash, the video game. When I click "Buy," I'm not at all expecting to "buy" a temporary, permanently revokable license to play the game for now. I'm expecting to own the 1s and 0s that are downloaded to my device. Hiding legalese in the T&C that nobody clicks saying "actually buy means lease" is legal, and it should not be legal, because it's misleading as hell. They should not be allowed to redefine widely understood words in T&C in a way that misleads consumers into paying for something they didn't expect to be paying for.
