So if Trump does the same, that's not the government saying it, because he also can't act unilaterally for the government, right?

And in fact, no individual politician should be capable of acting unilaterally for the government, so I guess they are all off scott free.

Trump is different. He is the executive branch. He has the ability to EO change without anyone else having to agree before the fact. The FCC operates as a commission. The chairman might set the agenda, but the commission has to agree by majority. You could argue that he has great influence within the FCC, but he is not the FCC.

When you make the leap from Carr to “the FCC” it’s roughly like if Sen. John Thune said something and you attributed his words to “the senate”.
