I wasn't touching on freedom of speech, just the relative quality of speech in both platforms.
As a centralized service operating in Canada and the EU though, I do believe Twitter is legally required to remove certain kinds of hate speech. The qualification for removal might be debatable (e.g. "the Austrian painter was right" is another thing people say which is a dogwhistle, but probably not explicit enough for companies to be compelled to remove it) but the requirement is there.

You know, reflecting back on my youth, I wish certain things I said (and might have posted on social media had it been so present) were immediately stricken from the record. Banning hate speech which incites violence against a minority group is a slippery slope, but I think it's for the better. At the same time, of course it can be abused, such as with the IHRA definition of antisemitism used in many jurisdictions, under which many valid criticisms of Israel would be deemed "antisemitic"
