The Sybase Open Watcom Public License is a software license that has been approved by the Open Source Initiative.[2] It is the licence under which the Open Watcom C/C++ compiler is released.
The license has not been accepted as "free" under the Debian Free Software Guidelines, due to the license's termination clauses.[3][4]
The Free Software Foundation (FSF) has stated that the license is not "free" as it requires the source to be published when you "deploy" the software for private use only.[1] In contrast, FSF's General Public License (GPL) does not require that a modified source code has to be made public when the software modification was only used privately without a public release of the software. This makes the Watcom license also GPL incompatible and a stronger copyleft license than the GPL and even the AGPL.
The Fedora project also considers the license as non-free, citing the FSF argumentation.[5]
History
Version 1.0 appears to have been written in 2002. It's publicly released no later than January 8, 2003, the date of the initial release of Open Watcom C/C++.
The draft of version 2.0 of the License was published on 20 January 2004. This version incorporated changes from Apple and made the licence less specific to OpenWatcom.[6][7]

This is not a free software license. It requires you to publish the source code publicly whenever you "Deploy" the covered software, and "Deploy" is defined to include many kinds of private use.
