As a graduate of the University of Oregon, BA '69 and JD '71, my personal experience as an undergraduate in the liberal arts was that 'freedom of speech', with some few fortunate exceptions, was freedom to regurgitate each particular professor's course notes in the style which he preferred.   Most were arrogant, extremely pleased with themselves and viewed undergraduates as unfortunate necessities.   Those few tenured who would deign to be in the same room with undergraduates were much worse.  I view tenure, like any union,  as a protection for the mediocre who would otherwise be required to actually be productive.
