Accepted Restrictions
Certain licenses restrict distribution in order to force derived projects to allow the freedom to use, study, modify, and redistribute the derived project. Some free software licenses carry requirements and restrictions which apply to distributors. There exists an ongoing debate within the free software community regarding the fine line between what restrictions can be applied and still be called "free".
During the 1990s, free software licenses began including clauses, such as patent retaliation, in order to protect against software patent litigation cases - a problem which had not previously existed. This new threat was one of the reasons for writing version 3 of the GNU GPL in 2006. In recent years, a term coined tivoization describes a process where hardware restrictions are used to prevent users from running modified versions of the software on that hardware, which the Tivo device is an example of. It is viewed by the FSF as a way to turn free software to effectively non-free, and is why they have chosen to prohibit it in GPLv3.

Famous quotes containing the word accepted:
“Genius is the naturalist or geographer of the supersensible regions, and draws their map; and, by acquainting us with new fields of activity, cools our affection for the old. These are at once accepted as the reality, of which the world we have conversed with is the show.”
—Ralph Waldo Emerson (1803–1882)
