So what would be the effect of terminating this program's copyright after 5 years? This would not require the developer to release source code, and presumably most will never do so. Users, still denied the source code, would still be unable to use the program in freedom. The program could even have a &ldquo;time bomb&rdquo; in it to make it stop working after 5 years, in which case the &ldquo;public domain&rdquo; copies would not run at all.
