Assuming these reports are true, it's difficult to determine the scale, magnitude and intensity of the effort being directed against religion. (Superficially) this doesn't seem comparable to the extreme lengths the Soviets went to in the 1930's, or to the Cultural Revolution in China itself, or to Albania's effort (the only communist state to outright ban religion). It is still a big shift away from the (relative) tolerance that saw religion grow over the 1990's in China. It's probably still "bad" though by any western standard of religious freedom and human rights.
The Soviet Union went through periods of liberalisation and repression of religion, with its policy changing over time. In the 1920's, there was an intense but very crude effort against religion: young communists would hold blasphemous rallies against Easter and Christmas, which the communists realised only pissed everyone off and entrenched religious believers. After a respite under the New Economic policy, In the 1930's there was intense efforts towards repression, with a "five year plan" to achieve the eradication of religion and the mass mobilisation of parts of the country as part of the "League of the Militant Godless". (They also adopted an entirely new calendar, which switched between 5 and 6 day weeks, thus abolishing "Sundays" so no-one could celebrate the sabbeth). In the 1940's, the war effort meant that this anti-religious campaign could not be effectively conducted, and there was a change in policy being more sympathetic to religious belief in order to help the Soviets win the Second World War. Under Khrushchev in 1950's and 1960's , there was a renewed effort towards undermining religion, but it was (comparatively) less violent; churches were closed, course in "scientific atheism" became mandatory in schools and universities and museums of atheism were established.
Probably the best example of what happened, in the difference between "liberal" and "repressive" periods, was the different approaches to eliminate Christmas celebrations. They tried it in the 1930's, declaring Santa Claus an "enemy of the people" and turning December 25th in to a "day of industrialisation" (celebrated by going to work...how inspiring...
) By the end of Communist rule however, people simply held Christmas-like celebrations on New Years as a way to find secular alternatives to it as a "communist" sponsored winter festival, with Santa Claus, "new years" trees and gift-giving. They also have "new years" cards, which you get a weird blend of seasonal themes and techno-Utopian or patriotic imagery.
