The person who posted this tweet and Yitong both believe this isn't a governance attack. Yitong describes it as a 'permissible action within the system's rules' and offers some suggestions on governance and security design. https://warpcast.com/yitong/0x0bf80ad8
The way I understood "governance attack" was that it's the crypto equivalent of the PE play, where activist investors try to extract value from the company. But I am an armchair quarterback, not a real expert here, haha. Anyway, I really like that Yitong also shared some solutions so that the whole community can learn from these stories.
