I absolutely just did this. Twitter burning down will make room for the next platform, which hopefully will be more resilient.
I'm also really praying that some super cool platform emerges from this that's convenient and fun and also somehow resilient against the whims of whacky billionaires.
There's no option "No you don't need to step down, just start running it well please, letting people say whatever they want".
There's no evidence "just start running it well please" is possible.
Do you mean that it's impossible to run Twitter well? Why is that, especially without needing to answer to shareholders.
Impossible in the abstract sense? No.
Impossible in its current state with its current leadership? All signs point to yes.
