Higgsfield promised to open source its product and never did.
ComfyUI's community built open source alternatives anyway.
Now Higgsfield sent a cease and desist demanding the challenge be taken down within 48 hours.
ComfyUI CEO: "When we started Comfy, we made the community a promise. Our product stays open, free, and yours. We've kept it every day since, and one letter isn't going to change that."
