> How is that 'partially irreversible' ... a bunch of companies paused ad-buys for this quarter or maybe even next year. If Twitter becomes viable next year, you think advertisers wouldn't come back, this year, or next, or year after that?

Any lost money is irrevocably lost. If I skipped on advertising in 2023 because I think Musk is an asshat, and then change my mind in 2024, I'm not going to double my budget to compensate. The money I didn't spend on Twitter in 2023 was spent on something else, and for Twitter was lost forever.
