Eurovision is one of the many competitions which do not give their winners the reputation of being "the best" according to their (pretended) criteria. Thus, anyone who competes in order to win such a reputation, is not in her/his right mind.

Most entertainers want to sell their records, and for that purpose, ESC is perfect.

Commercial entertainment as such is inevitable, and therefore not to be criticized wholesale. (I have worked for it, like presumably other Mudcatters.) However, state-run TV should insist on honesty and culturally valid criteria. More importantly still, it should resist nationalist tendencies rather than fostering them actively.
