SSPL does not violate OSD 6. It allows the Program to be used by
anyone for any purpose. If section 13 is triggered, there is a
copyleft condition that must be complied with. The SSPL is like many
other open source licenses, whose terms will naturally apply
differently to different groups of licensees. For example, most open
source licenses apply different conditions to software distributors
and software users -- not because the license discriminates, but
because those licensees choose to do different things with the
software. SSPL’s copyleft condition may require some users to release
more software than others, but that is only because those users made
different choices as to how to deploy the SSPL software. The license
does not set facially different rules for any field of endeavor.
