I'm not some free software zealot; I use macOS and the Creative Cloud and a bunch of other proprietary crap on a daily basis. I just don't pretend it respects my freedom. Nonfree licenses are like that.
It's not like it "switches to even more free": it is presently nonfree.
It's free for any use-case I'm concerned with. I can modify the source, self-host it, and run thousands of nodes through it if I want. All I can't do is take their work, slap my name on it, and sell it.
If that was your intent then VPNCloud is even less free. The GPL3 license means you could never host a closed-source version.
It's the AGPL that prohibits this, which is why I consider the AGPL nonfree.
The point being that any license is going to have some amount of:
> restricts the freedoms of the world to build upon, adapt, and use the software for any purpose.
It's just up to if you like the terms or not.
