Whats the recent relationship between Musk and Bezos? I know Bezos invests in Rivian and used their vehicles for Blue Origin/Amazon delivery. I don't know if they have the appetite for bailing out Musk even for a dollar. Bezos might rather enjoy seeing Musk crumble and take the blame for Twitter.
I suspect it only happens if it is good for Bezos. Maybe advertising Amazon stuff on Twitter and all that juicy tracking data of users would be worth it.
