Again, I understand where you’re coming from, but I don’t fully agree. While Threes was an definitely inspiration along the chain, by your logic, any creative work would need a detailed credit trail, even when it grows and evolves into something different. 2048 was not intended as anything other than an experiment, yet it took on its own life, driven by the unexpected virality and maybe by its simplicity. I’ve always tried to acknowledge Threes’ role, but I don't know that I should attach this label on every mention of 2048. I appreciate the perspective you shared.
What you are trying to do now is outright unethical.
