Game-Editor 2 now has its own website.
Technopeasant Looks like freeware though, not free software.
Game Editor 1 was and is open source. Game Editor 2 seems to be choosable: GPL or proprietary (if I understand Wikipedia correctly).
To me it looks like only the Game Editor 1 is GPLv3. No mention what so ever about the license of GE2 on the quick 10 minute search that I just did.
It also does not appear to be released yet as far as I can tell.
