I agree with you that there's been a shift in general attitudes towards freedom of speech. I disagree with you regarding where that opinion has shifted. Correct me if I'm wrong, but it sounds like you view this shift as occurring "across the board". I don't think that's the case. To me it seems that left-leaning people have shifted into very pro-censorhip views (against anyone who disagree with them), while right-leaning people have not shifted into pro-censorship views. You have now provided 2 examples of people who have (arguably) spewed hateful rhetoric, but didn't face harsh consequences for their actions. Both of those examples are left-leaning people. It does not strike me at all surprising that these left-leaning people were not censored, because the pro-censorship movement appears to be facilitated exclusively by people on the left, and of course they're not going to censor their own.
