List of formerly proprietary software
|This article is outdated. (January 2013)|
This is a list of notable software packages which were published under a proprietary software license but later released with the source code and a more liberal license. While such software typically becomes free software, open source software or public domain, also other constructs or licenses exist.
In some cases, the company continues to publish proprietary releases alongside the non-proprietary version.
