Proprietary Jails

Other examples of proprietary malware

Nonfree (proprietary) software is very often malware (designed to mistreat the user). Nonfree software is controlled by its developers, which puts them in a position of power over the users; that is the basic injustice. The developers often exercise that power to the detriment of the users they ought to serve.

Here are examples of proprietary operating systems that are jails: they are designed to impose censorship of which applications the user can install. The image of the iPrison illustrates this issue.

We also include specific examples of apps that were blocked using that censorship power. If you know of additional examples, please email the specifics to webmasters@ our domain.

These systems are platforms for censorship imposed by the company that owns the system. Selling products designed as platforms for a company to impose censorship ought to be forbidden by law, but it isn't.

Apple jails

iOS, the operating system of the Apple iThings, is the prototype of a jail. It was Apple that introduced the practice of designing general purpose computers with censorship of application programs.

Here is an article about the code signing that the iThings use to lock up the user.

Curiously, Apple is beginning to allow limited passage through the walls of the iThing jail: users can now install apps built from source code, provided the source code is written in Swift. Users cannot do this freely because they are required to identify themselves. Here are details. While this is a crack in the prison walls, it is not big enough to mean that the iThings are no longer jails.

Game consoles

No game can run on the console unless the console's manufacturer has authorized it. Alas, I can't find a article to cite as a reference for this fact. Please inform us if you know of one.
