Sure. It's just that if the goal really is to identify which stories aren't covered by news then if you only look at what news covers to determine that, you'll miss some of the bigger 'coordinated silences'. Weinstein's comment about how weird it is that no journalist ever brings up some really obvious questions about Epstein comes to mind. Or how little press there was about his brothers telomere story. From one perspective the reason for the silence is because it's not worth covering by the news, but from another perspective it's biased silence.
