Context: Kugelblitz is by one of the guys who made the original Terravision, which Google copied to make Google Earth.
Sadly, Kugelblitz is only available for Mac and is closed-source for now. And, of course, it's vibe-coded. He talks a little bit about his reasoning on his podcast (in German): https://logbuch-netzpolitik.de/lnp563-des-kaisers-neue-kleid...
Are you saying Keyhole copied Terravision when they created EarthViewer? Google Earth was a rebranding, with continued development, of Keyhole EarthViewer after Google bought Keyhole.
One out of two guys. Also, I listened to his podcasts for ten years, and he always had high standards. But 1. this gets really annoying, fast 2. Right now, he talks about a lot of stuff he does not know about as if he would know everything in the world.
Really can't stand him any more.
And yes, project is not even F/LOSS. 3D mouse recommended, this guy is aloft from the rest of human civilization.
