They do not. The UK, Europe, and '1st World' Western nations generally have subsumed speech protections, such as they existed, to the service of protecting classes of people that, in government's opinion, require extra protection or immunity to "discrimination". It has resulted in 'hate speech' legislations entirely at odds with free speech.
In the U.S., it took the form of "hate crime" as the acclimation doorway to condition us to penalizing thought and emotion; that is what hate crime does. It's disgraceful and we see the outgrowth in various forms which attack property, free association, and right to conduct business and earn income without government, social policy persecution. College campuses have been incubators of speech-fascists for decades.
Before the Trump presidency and subsequent election of Biden, I'd thought we might be 40-50 years behind Europe; now, I'd be surprised if it's more than 10-20. Currently, the 1stA prevents congress from directly violating speech. But, just as Marxo-fascists have always done, they leverage industry and media to do it for them. Leftists politicians openly prod big tech, print, radio and televised media to outright censor conservatives or otherwise dissenting voices.
In socialist governed countries such as China, S. Union, Cuba, NK, etc. government simply destroyed or placed proletariat-spouting technocrats in those entities to run them. In fascist countries, private ownership could retain ownership by compliance; "everything within the state, nothing against the state, and nothing outside the state." The corporatist model - the smiley-face fascist model - is to...encourage censorious action and advocacy according to party and ideology. This is what we're seeing in the U.S. To the rather small degree that media aren't already acting as Praetorian guard for the left, and industry to protect market hegemony.
