@[email protected] speaks unclearly when saying “public space”—the term they are thinking of is usually “public forum.” source
The rules around what constitutes a true public forum and what the public forum doctrine even means are fuzzy, but in all cases the term refers to a space owned or created by the government.
Thus, a shopping mall, parking lot, or internet forum, being owned by a private company, is not a public forum and can’t really be defended on the basis of the public forum doctrine.
Finally, as @[email protected] points out, none of this matters anyway in cases of incitement to imminent lawless action like threats or terrorist speech, which the First Amendment does not protect.

ooh its always so interesting to come across these. writing clear and effective english is a learned skill that isn’t the same as writing “correct” english. the author seems to rely heavily on indirect and passive phrases and poor preposition use which leads to a wandering feeling:
here’s the same quote, “fixed”:
it’s possible english isn’t the author’s first language, or they simply don’t have the communications education you are used to seeing in journalism. at least you know it’s not ai though :)
