>I'm confused as to why the US government would break up large tech now. Surely tech has reached the status of being a national interest, especially in relation to information and communication?

Harry Truman said in 1945 about the atomic bomb, "We thank God that it has come to us, instead of to our enemies". I feel the same way about FAANG and Silicon Valley as a whole (and Wall Street, and Hollywood, and SpaceX/Tesla, and the Ivy League), that they are in the United States.

That doesn't mean I approve of everything they do. That doesn't mean I can't or won't decry their putting thumbs on scales toward a certain type of bien-pensant ideology. That does mean that, overall, I am very, very glad that they are American instead of Russian, Chinese, or even British, French, or German.
