A similar example, people should be able to freely assemble, corporations should not be able to form cartels.
No, nobody truly believes that. Whoever is trying to sell that is trying to manipulate you. We have exceptions, provisions and considerable case law which adds a lot of *) to the first amendment. The 'principles' you're referring to have never actually been a thing outside of political emotional speeches and Republican rallies.
None of us have been alive when America was in a hot war to see exactly how far free speech stretches when actual lives are at stake. We're in a cold war right now and people should adjust their expectations. I'm not shedding any tears when a foreign corporation has its 'free speech' rights restricted. If it wants free speech it should move to the USA.
People like to think of themselves as being pro-freedom because it’s hip and cool and they are brainwashed from a young age to be proud to live in “the land of the free” but the moments you interrogate those beliefs a little they start to fall apart. It’s more of a political aesthetic than a true belief system.
