While I agree with you in principal, and I am not saying they would have a "valid" claim, but to prevent any confusion or problems, it just seemed like a wise choice from my perspective. You know how Patreon can be, and FAKKU is known for shady shit. To me, it's just best not to take any chances, but I haven't messed with both studios too much, so I can't say exactly how easy such a switch would actually be. I just know games like Headmaster are made in it, and it looks pretty close.
Hell, you could even just say you use the play home one, and who would even know the difference.
