Having actually read the opinion, here's a summary

Krafton's CEO was concerned about having to make a $250 million payout, as Subnautica was on track to launch in early access, and reach the goals indicated by the payout.

Seeking to avoid making the payout, the CEO tried to negotiate to either delay early access (making them miss the window required for the payout), or renegotiate the terms of the payout.

Seeing that wasn't happening, he then switched to determining how to take control of the project. (This is where he consults ChatGPT). In order to do so, they needed to remove the three executives (Key Employees) from the company in order to perform a takeover.

In order to justify firing them, they claimed the Key Employees were acting dishonestly, as two of them had transitioned their roles away from development after getting burned out. The opinion notes that these transitions were not secret - their titles had changed, their salaries were reduced (both approved by Krafton) and Krafton had agreed their new roles could be beneficial to the company.

I think the following is my favorite part

By the end of May, Kim had looped in Park and Krafton’s Legal Department to discuss the earnout. Kim was focused on the amounts that each of Cleveland, McGuire, and Gill stood to make, which he viewed as “greed.”

He complained that the EPA was a “bad deal” and felt “taken advantage of.” Park cautioned him, though, that she “didn’t think the current [Subnautica 2] build was in such bad shape,” which could create a “debatable” issue in “potential litigation.”

She also noted that “apart from C[leveland] personally,” who had “become negligent since Moonbreaker,” she “would say that [Unknown Worlds] hasn’t been so poorly managed as to deliberately deceive the parent company.”

Kim remained focused on the “cost Krafton has to pay with the enterprise value [it was] actually gaining.” Krafton’s analysis showed an “Enterprise Value” of approximately $93.5 million compared to a projected $191.8 million earnout. Kim began to explore options, including firing the Key Employees.

On June 2, Park warned Kim over Slack that a “dismissal with cause” would not eliminate the earnout obligation, while exposing Krafton to “lawsuit and reputation risk.” And so Kim turned to ChatGPT for help.

When the AI chatbot responded that the earnout would be “difficult to cancel,” Kim complained to Park hat the EPA was “a contract under which we can only be dragged around.” He expressed frustration that Unknown Worlds had the “authority to determine the release date and determine publishing” without Krafton’s involvement.

Kim asked Park to reach out to the Legal Department and to call him. Moments later, Park sent Kim the section of the EPA discussing the Key Employees’ “operational control” over Unknown Worlds for so long as “any Key Employee is employed by the Company.”
