From VOA:

The head of Russia’s For Human Rights organization, Lev Ponomarev, told VOA that Khodorkovsky’s imprisonment had a chilling effect on criticism by businesses of the Kremlin.

Ponomarev says Russia’s entire business community bowed to authority, served it, and filled its campaign coffers with money. He says he has seen no movements that would indicate the position of Russian business was different from that of the Kremlin.

The activist notes that many Russian businesspeople would likely share Khodorkovsky’s fate if they spoke out.
