Destroy the Google HQ, data centers, and assassinate it's leadership?
I mean he could maybe direct a Republican Congress to legislatively fine and tax Alphabet into the ground, but there are definitely a large number of Congress that have money in Alphabet.
He can't even come up with coherent rants, how could he come up with a way to fight someone as big as Alphabet.
Also, he, nor anybody else who would pursue something this dumb realize how many things run on google's cloud, middleware, SaaS products, etc. His middle schooler mind thinks "google = google.com search," when Alphabet's business is so much bigger than that.
