It is considered a best practice for web apps to open new browser windows in many situations because they are not blocked by the popup blockers built into browsers, they scale well to small mobile devices, and they can display files that are loaded locally on the user’s device.

Your company sells a device (smartphone, tablet, or other small portable device) for which owners can download third-party apps from your app store. The company’s published policy says that the company will delete an app from users’ devices if and only if the company discovers that the app contains malicious software such as a virus that compromises the security of the devices or of sensitive user data on the devices. The company discovers that an app has an undocumented but easily initiated component that displays extremely offensive video. The company immediately removes the app from its app store and alerts customers to delete the app from their devices. Should the company remotely delete the app from the devices of all who downloaded it? Give arguments on both sides. Which side do you think is stronger? Why?
