Why is Google allowed to remove purchases from our Play Store accounts without telling us?
(www.androidpolice.com)
A "purchase" or "buy" option, especially when you get an invoice, should ALWAYS mean ownership of the product.
A "borrow" or "rent" option is one that you expect to have to return the product.
Google can't have it both ways. They either sold people software or they rented it out. Since it was never advertised or marketed as the Google Play Rental Library, they should be forced to give people the products they paid for.
