Nonfree (proprietary) software is very often malware (designed to mistreat the user).

The developers and manufacturers often exercise that power to the detriment of the users they ought to serve.

This typically takes the form of malicious functionalities.


This page describes malicious techniques that proprietary software might use in the future for malicious purposes. We don't have any evidence that they are in use yet.
