I still feel like it should be illegal for the button to say "Buy" or "Purchase" when you're actually leasing the item.
There should be a nice, big, summarized disclaimer right above the button explaining what exactly you are purchasing. I'm sure the 100 page EULA explains but nobody has time to read through the whole thing every time they make a digital purchase.
Been saying it since I popped out the womb, I'm so happy to see more people share this sentiment. It doesn't matter that changing the definition of "buy" is legal when they put a tiny little link to a 30 page document above the big green "purchase" button. The fact that that's legal is the whole problem.
