The point of GPL licenses is to protect the user of the software, not the developer. If you want "protection" as a developer, use MIT (disclaimer of warranty). GPL "infects" other parts of a system to combat a work-around which was used to violate the software freedom of the user, by firewalling sections of GPL'ed code from the rest of the system. If you don't care about your users' software freedom in the first place, then (L)GPL is the wrong choice.

If any of them is missing or inadequate, the program is proprietary (nonfree)

However, the presence of nonfree software in the computer is an obstacle to verifying that the computer is loyal, or making sure it remains so.

For instance, the AMT functionality in recent Intel processors runs nonfree software that can talk to Intel remotely. Unless disabled, this makes the system disloyal.

Free/Open Licenses Non-free Licenses
