Just to be clear -- and fair to Disney -- they announced the changes to the TiW in August 2013. I cannot find the official press release but here is
an article from Aug 3, 2013 referring to it. The changes do not go into effect until August 2014, so they gave 1 year's notice -- entirely appropriate for a card that is good for 1 year (yes, I know it's more like a year and a month, but officially it's for 1 year). I know the information has been on the actual TiW website since August 2013.
I'm not defending the changes, but I don't see anything unfair about how Disney rolled them out. Just because this thread was started a few days ago doesn't mean that was when the news became public.
