I have just changed the ToC for #QOTO.. We replaced the phrase "free speech" With the more appropriate principle of "Academic Freedom". We also changed some subtle wording to be more explicit.
In practice our rules have not changed in any meaningful way. I may make some more tweaks soon.
All too often, "Free Speech" = "Freedom to yell fire in a theater," which is explicitly forbidden within the US despite the knuckleheads that don't seem to grasp the difference.

"Fighting Words" & "False Statements of Fact" among "forbidden free speech."
https://youtu.be/YI5orKCzz58 by @legaleagle covers some of the Alex Jones business, and he has another video he did on the topic before that one. "Freedom of speech" is touched on in various areas as it comes up.
