In the 1950’s Mao Tse-dong signalled a slight opening of Communist China. He announced the “hundred flowers campaign” encouraging disgruntled intellectuals and non-communists to speak up and voice their grievances.
When the most vocal ones raised their voices, they were thus found out and arrested.
I see a similar Communist strategy here - use the Christians to defeat the Christians.
This has been part of their scampaign strategy since losing in 2004.
