I don't understand the allegories to feudalism when jesters who crossed a line weren't censored but executed. (I would guess specially if they expressed or supported any sort of anti-monarchy or anti-their-monarchs viewpoints)

Actually, it was a chief job of the jester to cross the line when other members of the court could not. Jesters, as all court members, had a natural fear of execution, but probably not any higher than any of the other courtiers.

He had a slightly different line, but got executed if he crossed that one.

maybe peasant is a better allegory; he works the lord's lands solely at the lord's discretion, keeps a tiny share of what is produced and is ejected at will

I believe banishment was a much more common punishment in feudal kingdoms than execution.

Apparently some jesters were used as messengers during campaigns / sieges and if the recipient didn't like the message they would be trebucheted back to whomever sent them.
