> The accusation is that Young-Wan Kwon published the first paper without the consent of the rest of the LK-99 team, listed himself as third author, and left off the other four. Two hours later, the rest of the LK-99 team stuffed as much as they had into the second paper, and released it as soon as possible.

Kwon has already left the company early this year according to recent interviews. Moreover a supposed private communication with Auh [1] does suggest that Kwon was already offered an authorship in the joint 7-author paper but never replied back until the first arXiv submission went public. I don't know what Kwon actually wants out of all of this stunt, but it seems clear that there was already a big gap between Kwon and other authors and this "leak" only surfaced the gap along with LK-99.
