>>6425439It's TFW so take it with a grain of salt but here's a translation somebody there made of the tweets.
If any of this is to be believed, it sounds like the artist was never contacted by GT regarding use of his designs. He saw the reveal at TFCon and immediately contacted his friend at Takara to clear the air about him being involved. According to this translation, he's going to stop doing TF art, not because of fanboys or any of that shit, but because he doesn't want to risk getting involved in any legal gray areas where folks think he's turning a profit off of toys based on fanart designs.
It still sounds like he neither condones nor condemns the idea of the figures being made, he just doesn't want to risk getting into legal trouble or have his rep be damaged with folks thinking he's trying to use somebody else's IP for mass-produced merchandise.
Granted, I don't know much else about what went down on twitter in Japan-land (though I believe it probably was a fanboy shitshow) or how that may have changed his demeanor on the situation but it sounds like he has no intention of trying to stop the line, he just wants people to know he isn't involved.
