The BBC link accurately described the core of the issue, which is a typical case of a propaganda move, (in that instance, from the Russian government), with contradictory results, due to the different principles and perspectives between the Russian people and the western Europeans. From my experience (and the BBC article agrees with that), the eastern Europeans tend to care about international competitions, such as Eurovision a bit too much. Consequently, the authorities exploit these feelings, by either gloating and taking pride of occasional successes, thus increasing their popularity by linking the fortunate event to themselves, or vehemently protesting, in cases of the more frequent failures, trying to convince their voters that they take "national matters" seriously and passionately defend their country's interests. Of course, such initiatives, like government officials complaining about music competitions, are justifiably viewed by many people out of Russia as childish and ridiculous, but the authorities don't care much, since their target group is the Russian masses, not them.
