They've been giving those BS responses for quite a while, now...Even before Sports verdict.
It just doesn't make any sense considering the disclaimer (see below). If they simply kept the mail then their disclaimer would protect them, but by saying they 'deleted' it they, in essence, provide proof that they DID read the idea, and eliminate the protection that the disclaimer provided, especially if you or I publish the letter on, let's say, a Disney discussion board like this(which in itself 'logs' and dates the idea and ties it to the person). If Disney acted on one of our ideas received under the disclaimer, they could use it against us if we sued, whereas now we could claim that they read it on the discussion board (showing it was our idea before it happened) and stole the idea and they'd have NO protection. The way I see it they are cutting their own throat on several levels (fan input, diversified viewpoints and legally speaking). They should, instead, send an acknowledgement and reitteration of the disclaimer to further cement the protection, instead of elimininating it, and consider giving free passes and/or hotel stays to people who provide ideas, if used.
