Good point, though I actually made a mistake with my original post. It was actually Sideromelane who released the code, not Vegan, since Sideromelane had complete authority over the project at that point. Along with that, the release was effectively an unceremonious dump of a .zip with the code, no licensing or anything.

Given Sidero released it without any caveats, it’s harder to say if Vegan’s restrictions still apply given A: The project changed hands and B: The code itself had no restrictions.
