I just found about this distro, which is relatively new (2021). Its specificity is that it doesn’t features any GNU software by default, which I find interesting.
Yeah, you have the choice of have your software be controlled by companies that could just stop licensing it.
But the point of GNU is to disallow closing down sources. Companies don’t like that, because it’s not profitable. They need non gnu stuff so that they can build money printing closed gardens with it.
Not using GNU software doesn’t mean you don’t use any copyleft licenses or GPL.
GPL, also known as GNU GPL. https://en.m.wikipedia.org/wiki/GNU_General_Public_License
The reason for non GNU distros is to maintain the right of closing down the source of whatever product you build with it, disallowing the customer’s software freedoms.
It would be pointless to have a non GNU system with other copyleft protections, because that’s counter to the reason why they exist, in the first place.
