Compared with other "licensed" free software license agreements (such as BSD license agreement), the main difference is that p>GPL seeks to ensure that the above-mentioned free energy is guaranteed in copies and deductive works. It is realized by a legal mechanism called Copyleft invented by Stroman, which requires that the deductive works of GPL programs should also be under GPL.

on the contrary, BSD-style license agreements do not prohibit deductive works from becoming proprietary software. For some reasons, GPL has become the most popular license agreement for free software and open source software.

by April 24, GPL had accounted for about 75% of the free software listed on Freshmeat and 68% of SourceForge. Similarly, a survey on Red Hat Linux 7.1 in 21 showed that the general code was published in GPL. The famous GPL free software includes Linux kernel and GCC.
