Yeah I was too negative. Vendor lock-in sucks so I'm glad someone is tackling it and I should have started with that.

But I think people shouldn't hold back criticism either just because something is free or open source. Stability AI (Stable Diffusion) just sold out and took $100 million from investors after being open source. Even if they're providing something altruistically now you never know if that will change after VC, buyout offer, or some other event.

But the open source code is still there, the community is always able to fork and continue development. True, that rarely happens, but does occasionally (e.g. Emby -> Jellyfin).
