Elizabeth Warren, prominent antitrust academics, and even a Facebook founder, have all called for an antitrust suit to breakup Facebook.  Now state attorney generals have announced an investigation.

But breakup advocates should be careful what they wish for because the real problems Facebook creates—addicting people like a drug, promoting fake news, allowing a foreign power to tip a presidential election, allowing mass murderers to broadcast their massacres, and diminishing our privacy—are all likely to be aggravated, not mitigated, by a breakup.
