[单项选择] In recent years, we have all watched the increasing commercialization of the campus. The numerous advertising, posters and the golden arches of fast food outlets may be an affront (侮辱) to our aesthetic sensibilities, but they are, arguably, no worse than ugly. Some of the other new features of commercialized campus life do, however, constitute a serious threat to things we rightly respect. "Privatization" and the "business model" are the potential menace. What do these notions mean To me, they involve an increased dependence on industry and charitable actions for operating the university; an increased amount of our resources being directed to applied or so-called practical subjects, both in teaching and in research; a proprietary treatment of research results, with the commercial interest in secrecy overriding the public’’s interest in free, shared knowledge; and an attempt to run the university more like a business that treats industry and students as clients and ourselves as
A. more convenient
B. rather ugly
C. somewhat harmful
D. no more aesthetic than before
