OK, you're right, it'd probably be trademark, not copyright claim, though the difference in effect is minimal. And they did try to trademark Dia de Los Muertos

OK, you're right, it'd probably be trademark, not copyright claim, though the difference in effect is minimal. And they did try to trademark Dia de Los Muertos and did trademark words "Hakuna Matata", so it wouldn't be out of character for them. As for whether they initiated it, given that things with Loki on it start disappearing right when Disney premiers it's new series called Loki... I'd call it a bit too much of a coincidence. > and it doesn't mean the rights holder filed anything. The article says: "The rights holder, in this case, is indicated to be Disney Enterprises, Inc.". So apparently the rights holder did something, otherwise how would Redbubble know who holds the rights?
