LF is like etcd or consul (or so far just the data store aspects) but for decentralized systems that can be run by multiple parties across trust and organizational boundaries. It's an orchestration backend for decentralized apps.
We are going to use it to fully decentralize ZeroTier and for some specific enterprise customer projects, but others can use it for other stuff.
I'm curious to understand why you're so anti-GPL though. Linux is GPL and it hasn't stopped people from using it.
The GPL is not perfect but at the time we adopted it there were no other good alternatives except more permissive licenses that would have led to other companies just taking our stuff and monetizing it without compensation. We are not interested in charitably donating free labor to Amazon.
