How do proprietary software licenses typically differ from open source licenses?
Proprietary licenses, such as those from Microsoft or SAP, are tailored specifically to their products and restrict the user’s rights in various ways. Open source licenses, however, aim for clarity and general validity, allowing users to understand, use, and modify the software.
What is the copyleft principle as defined by the Free Software Foundation (FSF)?
The copyleft principle mandates that modified versions of software must also be free, ensuring that the liberal principles of a software license apply unrestrictedly to future variants of the software to prevent subsequent restrictions.
What is the GNU General Public License (GPL) and its significance in open source software?
The GPL is one of the most important licenses for free software formulated by the FSF, used by many projects like the Linux kernel. It ensures that software remains free and open, requiring any derivative works to also be open source under the same license.
Describe the GNU Lesser General Public License (LGPL) and its use case.
The LGPL is a variant of the GPL that allows free software to be linked with proprietary software, typically used for libraries. Modifications to the free software part must be open, but proprietary code can remain closed.
