There's a really interesting comment on that, @DisappointedReader -- a poster called Julia Tarry says 'How sad that anything nice has to be destroyed'.
That to me is the exact sentiment that seems to motivate a certain type of response to the CH investigation. They blame, not SW for deceiving them, but CH for pointing it out.
TSP was 'nice', so their loyalties lie with that niceness rather than the 'not-nice' exposé.
It's a version of shooting the messenger. Or 'If you can't say anything nice, don't say anything at all.' In this worldview, CH is guilty of bad manners, of being the one to say 'We all know your Derek was shagging Natalie from the pub' at a dinner party.
And another poster on Coverack Life seizes on the fact that CH's reporting has been contested on other stories she's investigated, not appearing to realise that this is the nature of investigative journalism, not that CH is some kind of skeezy, disreputable knicker sniffer who goes through bins looking for celebrity secrets and publishing rumours. The same poster quotes SW's statement as though it refutes the Observer story.
Someone else says 'So sad, because most of us love the coastal paths around Cornwall'. It's not clear what she thinks is 'sad', the scam somehow smearing the SWCP, or CH for bringing a lovely story about the SWCP into disrepute.
