Proprietary Software Is Often Malware

Proprietary software, also called nonfree software, means software that doesn't respect users' freedom and community. A proprietary program puts its developer or owner in a position of power over its users. This power is in itself an injustice.

The point of this page is that the initial injustice of proprietary software often leads to further injustices: malicious functionalities.

Power corrupts; the proprietary program's developer is tempted to design the program to mistreat its users. (Software whose functioning mistreats the user is called malware.) Of course, the developer usually does not do this out of malice, but rather to profit more at the users' expense. That does not make it any less nasty or more legitimate.

Yielding to that temptation has become ever more frequent; nowadays it is standard practice. Modern proprietary software is typically a way to be had.

As of October, 2019, the pages in this directory list around 400 instances of malicious functionalities (with more than 500 references to back them up), but there are surely thousands more we don't know about.

Back door: any feature of a program that enables someone who is not supposed to be in control of the computer where it is installed to send it commands. Digital restrictions management, or “DRM”: functionalities designed to restrict what users can do with the data in their computers. Jail: system that imposes censorship on application programs. Tether: functionality that requires permanent (or very frequent) connection to a server. Tyrant: system that rejects any operating system not “authorized” by the manufacturer.

Users of proprietary software are defenseless against these forms of mistreatment. The way to avoid them is by insisting on free (freedom-respecting) software. Since free software is controlled by its users, they have a pretty good defense against malicious software functionality.

Latest additions

Apple plans to require that all application software for MacOS be approved by Apple first.

Offering a checking service as an option could be useful and would not be wrong. Requiring users to get Apple's approval is tyranny. Apple says the check will only look for malware (not counting the malware that is part of the operating system), but Apple could change that policy step by step. Or perhaps Apple will define malware to include any app that China does not like.

For free software, this means users will need to get Apple's approval after compilation. This amounts to a system of surveilling the use of free programs.
The Chinese Communist Party's “Study the Great Nation” app requires users to grant it access to the phone's microphone, photos, text messages, contacts, and internet history, and the Android version was found to contain a back-door allowing developers to run any code they wish in the users' phone, as “superusers.” Downloading and using this app is mandatory at some workplaces.

Note: The Washington Post version of the article (partly obfuscated, but readable after copy-pasting in a text editor) includes a clarification saying that the tests were only performed on the Android version of the app, and that, according to Apple, “this kind of ‘superuser’ surveillance could not be conducted on Apple's operating system.”
Apple censors the Taiwan flag in iOS on behalf of the Chinese government. When the region is set to Hong Kong, this flag is not visible in the emoji selection widget but is still accessible. When the region is set to mainland China, all attempts to display it will result in the “empty emoji” icon as if the flag never existed.

Thus, not only does Apple use the App Store as an instrument of censorship, it also uses the iThing operating system for that purpose.
Apple has banned the app that Hong Kong protesters use to communicate.

Obeying the “local laws” about what people can do with software is no excuse for censoring what software people can use.
Adobe has cancelled the software subscriptions of all users in Venezuela. This demonstrates that a subscription requirement is a potential tool for sabotage.
