Who funds those tech firms? It's not Trump. His power is mostly theater to his constituents and those who funded Trump: spoiler: he's not entirely self funded, and some of his funding is at least from others so he's conflicted in his self interests to others. We call this a classic conflict of interest.
Yeah I can see that. Though the separation between "govenrment" and "corporation" is pretty thin already. So nationalization or corporitization, whatever you want to call it, its just a label for rich and powerful people concentrating power and deriving benefits.
