e/Commercial open source software

Information
has gloss	eng: Commercial open source software (COSS) is software that contains some elements of free and open source software in order to legitimately claim to be "open source", however sometimes also limits availability of some generally enhanced functionality to proprietary software which it sells under a closed and limited license . The release of some code under closed licensing builds in a potential path back to vendor lock-in if the functionality is ever required, and so the overall software is not "free" in the original sense and so does not qualify as FOSS as a whole. The right term for these "mixed-source" applications, and the term many of the companies behind them prefer, is COSS.
