>but I feel sometimes the historical perspective is a bit lost.
How is the "historical perspective" relevant here? Are you just arguing "we actually have it pretty good right now compared to the past so we shouldn't feel so bad about freedom of speech slipping"?
When it's presented as a near-existential threat then I think it's important to keep some perspective, and it clarifies that "free speech absolutism" has never been a particular common or popular stance.
I'm not saying things are perfect or that there aren't any problems, but I feel sometimes the historical perspective is a bit lost.
