Epic has also been working on this for longer than the three months your repo has been around. This is the launch of the open source project and independent GUI, but it was already integrated with their Fortnite game engine before now.
Your VCS repo is called "Artifact". It seems like a stretch to say that somebody using "Lore" is copying from you. Even if it were called "Pagan" that's still a stretch, but "Artifact" especially so.
I think a VCS written in Javascript is also inherently a nonstarter for any kind of production-grade use case. The idea that nobody else can make a gamedev-oriented VCS because somebody in the world made a little hobby project along those lines is frankly ludicrous.
(Granted, I'm not exactly keen to use Lore myself given the heavy signs of vibe coding throughout the documentation and repo. A vibe coded VCS is also inherently a nonstarter. Here I'm hoping some third party will come along and do VCS for gamedev right!)
I'd also add that there's some element of hypocrisy to criticising Epic here when your own marketing pitch is "I copied Git".
