> 2. Even if you fork a project in complete compliance with a software license, a software license doesn't grant you an ongoing business partnership

That's fair, I'd just argue it's akin to to Red Hat's current model of "All of our code is free and open source...but if any of our business subscribers share it, we will terminate their license."

It's not even that -- OnlyOffice hasn't terminated anyone's license. It's more like: Linus allows me to fork Linux but he's not going to join a Zoom call with one my customers.
