From the Proton/X discussion in the Intercept article

"Big Tech CEOs are tripping over themselves to kiss the ring precisely because Trump represents an unprecedented challenge to their monopolistic dominance.”

They don't know how this is going, from what I see Trump threatens something not to change something, but to get something. If there is any anti-trust drive it's there to shake the tree, not to break up big tech. Trump loves big US corporations, like those in the 50s and 60s, those pre-Bell-breakup.
