Except that Randy's article doesn't really tell us much either. He basically draws a (quite logical) conclusion that WN's changes are likely to cause other carriers to reassess their own programs, especially if the changes prove to be beneficial for WN. He makes too much about a "no comment" statement, sure, but there is nothing other than speculation to his article.
Are changes coming at some point in the future? Probably. I don't think anybody doubts that. What I think people doubt are the specifics people latched onto here. More importantly - and Randy's article speaks to this - I think people don't buy into the idea (implicit in so many of the comments here) that this is somehow DL-specific.
