Modern Society Can't Be Free Without Free Software

Modern society can't be free, while using non-free software.

When using proprietary software, it is now, in many cases, global corporations that control people's devices and computations; which national governments have little control of.

For instance, government can only control cable providers and ISPs, to block or unblock certain services or web sites, but it can not disarm mass surveillance on people's devices (known malicious software like Apple OS X, Microsoft Windows or Google Android); it may only be done by people themselves, boycotting these companies and using free software.
