Before shouting out your opinion, you're probably wondering what in the world the Open-Source movement is. The open source movement is a broad-reaching movement of individuals who support the use of open source licences for some or all software. Open source software is made available for anybody to use or modify, as its source code is made available.
There seems to be a marginal influence from the open-source movement on attitudes toward copyright in general.
There is also an interesting issue in connection with the copyright of interface specifications, which affects the interoperability of open source programs with proprietary ones. In some cases, several companies have been forced to give access to in-depth information on the workings of a program or operating system, to allow developers to extend and integrate the software component in their systems or programs.
