This is not new. There has been a lot of negative publicity concerning esp. abuse and DF practices among JWs for decades in the Scandianvian countries, esp in Denmark and Norway, but lately Sweden has had an increase in bad JW publicity. Also in Finland there has been a lot of TV/media coverage on JWs.
The August peak point of Norway was close to 12,000 (ca. 11,700). When i left the witnesses more than ten years ago they had about 10,500 reporting at most as far as I remember. Considering Norway is a very secular country, this number is fairly "good" seen from the witnesses point of view.
