I get your point, Henry.
However, once something is posted and has been removed, then that’s censorship.
There’s lots of reasons for censorship.
The reasons you mention are certainly justified. But then again, requiring another to bow to authority, even if the other is a vagrant guest enjoying a bit of light at the edge of the campfire that another has built, encourages the view of, “Whose bread I eat, his song I sing.”
Does that encourage philosphy?
These conditions here are not completely capricious.
The host and his agents have provided guidelines for the guests.
