There has been soo many posts on the subject and I dont remember all of the writes, but @pawsdog has written several articles on this whole "war" and the fires shot from both sides. So you can get a pretty good idea of what has happend from reading his articles. He is very objective in his research, and his posts are well written and worth reading.. Good discussion in the comment sections as well :)
