>By nearly every measure Twitter is doing a lot worse than it was before those people were fired.
Care to share which measures are those you speak of?
From what I saw, Twitter's revenue went down only due to the post pandemic economic slump following the pandemic bubble, and due to advertisers leaving en-masse because Musk won't purge the platform of hate speech and other content that's non advertiser friendly, not due to the workers who got fired leaving.
