Why is Google allowed to remove purchases from our Play Store accounts without telling us?

This is a most excellent place for technology news and articles.
They’re not purchases, they’re leases.
Edit: it’s actually that you purchase access to their license of the media.

They're not really leases either. Leases last for a defined period of time, like "one year," or they renew at regular intervals, like "monthly." "Pay up front and we'll let you keep this license for either forever or until we decide to revoke it without notifying you" isn't the same thing.
