They don't have to be broken up, they need to stop being morally bankrupt.

Nothing about Facebook's size dictates that they needed to:

- Allow their platform to be abused by misinformation campaigns, because it pays well (thereby allowing Trump to win)

- Allow hate groups to flourish

- Allow anti-vax groups to grow and flourish

- Allow nutty conspiracy groups to flourish

- Help dictatorships with their genocide

It's simply because they are morally bankrupt by design and by culture.
