This was a really dumb, completely avoidable blunder on 4H's part. I can only assume they've just gotten careless over the years with all their MOTU and now Conan homage figures.
However, the real reason I felt like commenting is that the Red Sonja character we know from popular culture already toed the IP line with Howard's Red Sonya character when Marvel was publishing Conan books in the 70s. Whether Marvel should have been able to copyright that character in the first place is debatable, but they were granted the copyright anyway. Red Sonja, LLC now owns the Red Sonja copyright, but they have to license all of her world and supporting characters from Cabinet Entertainment, who owns all the rest of Howard's IP. As far as I can tell, both Red Sonja, LLC and Cabinet Entertainment are just IP holding companies, i.e. parasites who buy up lapsing IP and contribute nothing of value to society.
Stealing IP from creators is indefensible. Stealing IP from IP holding companies is textbook Robin Hood shit and should be encouraged and applauded.
