You could make the same argument against every civil liberty the Germans enjoyed in the Weimar Republic: freedom of movement, freedom of press, freedom of assembly, even democracy.
That’s exactly my point, the Nazis never acted in good faith, they were never beholden to the freedoms they used, in fact they used those freedoms to get rid of them, so to protect them we have to restrict them. So unfortunately we have to exclude some things from the protection Democratic values can deliver. For example the swastika in Germany - all it represents, all it refers to in that context is anti democratic, anti freedom so if you show it outside of a educational context we have to assume it represents exactly that - that you want to get rid of democratic values like free speech, so we exclude that symbol from the protection of our democratic values TO protect said democratic values.
It’s a little paradox and a lotta complicated. We should never take those measures lightly but imo they have to exist, because history showed that if you don’t protect them , some forces are willing to use them to destroy them.
Your first link shows what happens when we don’t apply those measures carefully and too broadly, the framework has to be very precise for them to make sense, otherwise they do the job of the deconstructors of democracy for them.
Your second Link refers to a private entity, those can not restrict free speech, they can censor what speech they want to host and it is their right under free speech to do so, so it is irrelevant. Like if you’re in my house talking shit I can kick you out, no free speech was impeded by that action, I just exercised my free speech to show you the door.
