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.

==Permissive licenses==
The other kind of licenses, permissive licenses, allows usage of code without having to relicense it under the same conditions original code uses, thus allowing for more liberties for both programmers and users. The most known permissive license is the BSD license, but lots of other licenses are used in practice. Many businesses prefer using permissively-licensed code, as the licensing terms are more comfortable in their cases.
