A classic example of this kinda suppression of healthy opposition is the bbc's fleeting exposure of critical comments by senior officials of Greenpeace (and others) re issues covering the Brit govt's pursuit of oil production off Shetland and their withdrawal of financial support for a flagship decarbonisation project in NE Scotland - note this was a project promised to come to fruition by the "better together" mob, Cameron et al, preceding the Scot referendum vote in 2014. Another Tory promise, one of many, "buried in the sand"!!!
