Avoiding Vendor Lock-in For Computer Software

In the 1980s and 1990s, public, royalty-free standards were hailed as the best solution to vendor lock-in. But there is still a possibility that one software vendor could use "embrace, extend and extinguish" (EEE) tactics to achieve a dominant market share, which could render the standard obsolete. The history of SQL is an archetypal example.

Since the late 1990s, the use of free and open source software (FOSS) has arisen as a stronger solution. Because FOSS can be modified and distributed by anyone, the availability of functionality usually cannot tie a user to one distributor. The ineffectiveness of distributor lock-in means there's no incentive for FOSS developers to invent redundant new data formats if usable (royalty-free) standards exist.

In particular, copylefted FOSS is in some respects particularly resistant to the above mentioned "EEE" tactics since anyone distributing modified versions cannot legally prevent free or competing redistribution of the modifications and their source code. It is also, however, particularly well suited to those tactics in other respects, such as in competition with non-copyleft free and open source software.

Famous quotes containing the words avoiding and/or computer:

    There is all the difference in the world between the criminal’s avoiding the public eye and the civil disobedient’s taking the law into his own hands in open defiance. This distinction between an open violation of the law, performed in public, and a clandestine one is so glaringly obvious that it can be neglected only by prejudice or ill will.
    Hannah Arendt (1906–1975)

    What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.
    Rudolf Arnheim (b. 1904)
