That is quite disappointing. I’ve also noticed that many other filament clips are part of the exclusivity program, and I’m curious to understand why mine did not qualify. Since the qualification rules are not clearly outlined, I can only assume it is at the discretion of whoever is evaluating the submissions.
Additionally, I came across something important in the terms:
If a Creator discovers that their Exclusive Program Model is being used without authorization on other 3D model channels or platforms, we suggest that the Creator acts promptly to have the Exclusive Program Model removed to maintain their exclusive status on MakerWorld. The creator shall preserve evidence of their correspondence with the respective website operator, including the date, for future verification. You are solely responsible for taking any action necessary to protect and enforce your rights in your Model.
This effectively places the burden of policing the internet on the creators themselves. If your model is stolen and distributed elsewhere, you risk losing your exclusive status and, as we’ve seen, 100% of your model points.
