All the sculptor drama of "who copied who" is very silly. None of those dolls are that original! They are all humans in various forms of stylization. No one has dibs on any particular style of body just because they (wrongly) believe they did it first.
Accusing people of copying your joint "designs" is just as dumb. There's a limited amount of shapes you can give your joints and I guarantee you, you didn't invent any if them! Gatekeeping BJD mechanics will hurt the hobby in the long term, if no one took inspiration from well posing dolls we would still be stuck in the era of "can't even sit straight"-dolls.
To everone involved: It makes all of you look self-centered, jealous and unprofessional. Other artists existing and making similiar looking dolls is not a threat to you!
Step off your high horse and just focus on improving your art.
