Some background from HuffPost recently, echoing many of the other reports I've linked on similar threads about this not just being a JW issue:

Many people expected a flowering of faith when the Soviet Union disintegrated in 1991.
But it hasn’t happened, largely because the countries that emerged from the ashes of the USSR have repressed most religions, the main exceptions being Russian Orthodox Christianity and certain brands of Islam.
The repressed have included denominations of Christianity that are widespread in other countries, such as Catholics, Baptists, Methodists, Lutherans and Presbyterians.
As with other regrettable trends in the former Soviet Union, Russia has set the tone for the repression of religion.
