Also, stuff like this is actually happening for decades on the internet, way before the public domain came back in 2019.

The only difference is that now, this can be done without being hidden, it won't stay on a meme website, a webcomic website or on small YouTube channels, this can be shown on movie theaters or released on Steam, that's the difference.

Internet became a place where since nothing is in the public domain, then everything is in the public domain, grabbing a frame from SpongeBob and adding text, is illegal.

Public domain means all eggs don't have to be in one basket anymore.
