Isn't that the pro-Altman argument? The pro-Altman side is saying "let's shut the company down if we don't get our way." The anti-Altman side is saying "let's get rid of Sam Altman and keep going."
The board-aligned argument seems to be "destroying the company is the right thing to do if it helps the cause of AI alignment".
Whereas the pro-Altman side seems to be "if you have the most successful startup since Google/Facebook, you shouldn't blow it up merely because of vague arguments about << alignment >> ".
... But they aren't the ones blowing it up? Firing one guy, even the CEO, isn't blowing it up. The only side that directly threatened "if you don't do X, we blow it up" was the pro-Altman side.
