Found the following article online, use it to answer the question: What is the full name of the person who criticized Putin for supporting the reintroduction of the Soviet-era national anthem?

The federal legislature established and approved the music of the National Anthem of the Soviet Union, with newly written lyrics, in December 2000, and it became the second anthem used by Russia after the dissolution of the Soviet Union.
