A lot of folks didn't like the proposed 7e rules because of rumour, fear and doubt. There was a lot of misinformation repeated as fact and that led to quite a few people proclaiming their dislike without ever having seen the revisions.
I did two rounds of playtesting in the UK and I got the impression that not a few US people shouted their hate for 7e purely because it was a couple of UK-based authors despite the status of those authors in the Cthulhu gaming community. The playtesting did include a large number of groups although not, it appears, some of the most vociferous 'haters' who continue to trumpet their dislike for the revised edition.
