Fair-code is not a software license. It describes a software model where software:
- is generally free to use and can be distributed by anybody
- has its source code openly available
- can be extended by anybody in public and private communities
- is commercially restricted by its authors
It’s GPL, they have to also provide the source. And you benefit from all the rights they do.
“Business” licenses try to prevent competition while still benefiting from free contributions, and pass it as “fairness”. But how is it fair for anybody except that particular company? What about the contributors? If OBS used such a license and reaped all the benefits would you still contribute to them?
