It is childish to continue to push unity: A) Warren is not going to win, that's clear, B) It seems like this was all done to help ensure Biden wins, C) It was done with her blessing.

I think this is all true. As near as I can tell the only reason Warren entered the race is to be a spoiler candidate against Sanders to make sure he did not get the nomination and that Biden does. Nothing else makes sense given the latest events.
Biden will get the nomination, will lose without much of a contest to Trump, billionaires and millionaires are happy, and all is right with the world (from their perspective).
