> Most on the left would consider it authoritarian despotism if Trump started "Confiscating" companies. Most on the right would consider it the same if Biden or whomever did the same.

Eh. I disagree. It really depends on the company, the why, and what's done with it afterwards.

If the other party nationalized the big frontier labs or AI data center operators, with the rationale that AI is just too disruptive to privatize the gains and/or the companies are acting recklessly, I wouldn't consider it "authoritarian despotism," and I don't think many others would either: those companies are unpopular across the political spectrum.

There's a certain amount of reflexive opposition to "the other side," in that some people will oppose anything it does, but that's just really dumb, so I wouldn't read too much into it on any particular issue.

Now, if the Democrats confiscated "The Trump Organization" on some flimsy rationale because they really hate Trump, that particular action would be seen as you describe.

> In general, the US has strong opposition to the state unilaterally confiscating companies

Thankfully, things can change.

That's a dumb argument. "Confiscating companies" is not the reason those regimes are considered bad. And the fact they did some particular thing is irrelevant. I'm sure they also penalize murder, and your not going to get me to question my opposition to murder by saying "the Nazis had anti-murder laws!"
