If I created an amazing enough animation that random strangers on twitter recognized it... I mean, I'd say that if you're getting called out for using it and removing the artists name that's pretty amazing in general even if it sucks in this specific instance.
I find it shocking that strangers would actually stand up for an artist on the internet that seems to be having their work used without permission. Shocking in a good way.
Easy enough to address I hope with a note from the artist, though maybe I underestimate how fast Twitter dog piles happen...
