Article is spot on about the corruption - if anything, the tone is too mild - but overall I can't say the situation for businesses has become worse since the 90s. Police methods have simply displaced blatantly criminal methods from the ecological niche :-) Yes, today businesses get taken over by corrupt police and courts. In the 90s it was done by kidnappings, soldering irons and automatic gunfire in the centre of Moscow. And also corrupt police and courts.

Disclaimer: I'm a Russian living in Moscow. Wouldn't dream of starting a business here. Life as a programmer is pretty nice, though.
