@bookstardust Yep, that's true. Most especially Disney.
They did everything to delay the early versions of Mickey and Minnie entering the Public Domain twice by 20 years each. And already “reminded” people that they will “protect their brand” as it has become their image, and it is their Trademark.
It wouldn't be surprising if they already played different scenarios and already have a “bible” on what to do in each possible case. Disney is definitely not happy.
