Who else agrees that the play store should have a section which tells if an app needs a mandatory login to use it ? Like why the hell does a simple offline planner todo app need you to sign-up if you don't wanna use cloud backup. Jeez the user just trusted you by spending valuable time and bandwidth downloading your app. You owe it to him to show him some features of the app before shoving a sign up in his face. As an app developer myself I really think that this kind of behaviour turns off more users than anything else.
