Proprietary software

Definition and stakes

Andrew Morin; Jennifer Urban; Piotr Sliz,  A Quick Guide to Software Licensing for the Scientist-Programmer…

“ The primary purpose of a proprietary software license is to limit the use of software according to the rights owner's business strategy. As a result, proprietary licenses are often very restrictive for end-users. They typically allow use of the software only for its stated purpose, often only on a single computer, forbid users from copying, redistributing, or altering the work, and specifically prohibit the creation of derivatives using parts of the work. ”

“ The licenses for most computer software programs are designed to take away Your freedom to share software or change source code. This kind of software is designated as proprietary or "closed." The Hacktivismo Enhanced-Source Software License Agreement — like other license agreements that have served as inspiration for our work — is intended to promote both Your freedom to share our software with others, and Your freedom to change and improve the software. ”

“ More and more people are looking for ways to avoid the inflated price of proprietary software. A growing community contributes in appreciation for all the great free software they’ve received from others.
Many in academia create free software to help get the results of their research into wider use. Businesses help maintain free software so they can have a say in how it develops—there’s no quicker way to get a new feature than to implement it yourself or hire a consultant to do so! Business is also interested in greater reliability and the ability to choose between support vendors.
