@8r0fHA6ZurxVDP19vBJx Although it's not a direct comparison, Font Awesome Free doesn't use OSI-approved #opensource license.
https://opensource.org/licenses/
It's not software, so it's fine to use Creative Commons Attribution 4.0 International: https://github.com/FortAwesome/Font-Awesome/blob/6.x/LICENSE.txt
That's why it was forked into Fork Awesome and is available under OSI-approved license:

I consider Font Awesome source-available with a generous free license.
I'm not a legal expert, just how I interpret it 🤷♂️
