Copyleft as a mechanism requires that any software which uses code from copylefted software to be licensed under the same terms -- making it copylefted as well. In the long run, this will lead to more and more software being licensed under copyleft terms. Not only that, but, due to the nature of copyleft, a lot less diversity in licenses is possible -- in fact, the most popular copyleft license, the GNU General Public License (GPL), is used for the majority of copylefted software. If this tendency will not be stopped, all open source software is soon to be licensed under one license. | Copyleft as a mechanism requires that any software which uses code from copylefted software to be licensed under the same terms -- making it copylefted as well.
