I am starting to work on a new commercial software project that may use elements of "open source" code.
I have been instructed to ensure that I only use code which is licensed for commercial use and although we may decide to make it open source in the future it should be required to be open source.
So this clearly prohibits the use of any true copyleft licensed code.
But this got me wondering; are there any standard "open source" software licenses that allow commercial use, but do not allow redistribution of source?
I have intensionally used quotes around open source as I am aware that any licenses that fit this criteria cannot be compatible with the accepted OSI definition of open source.
