Changing the ownership does not address the problem, which is market concentration. You're still left with a company with too much power. That aside, look at the historical data. Nationalization has generally been disastrous and leads to all sorts of other pathologies.
Democracy allows authrotarians to rise in and of itself. Recent ones include Orban, Erdogan and Trump. Historical ones include, yes I know, Mussolini and Hitler.
This is just a lazy attempt to tie one thing to another, unpopular thing. What is the comparison here aside from "I don't like both"? In what sense is nationalization "corporate civil asset forfeiture"?
Not all nationalization is uncompensated, even in the real world. Further, you can imagine very fair ways, long term, to nationalize companies by e.g. requiring them to pay a wealth tax in the form of equity.
