That's like saying we shouldn't use the envelope to represent email, because no one sends snail mail any more. The save icon concept makes no sense to me either, it really doesn't represent anything related to save, maybe download but without the word "save" next to it I would not have associated the two (and to me looks like a copy of the Burton Snowboard icon https://www.google.com/search?q=burton&tbm=isch https://www.google.com/search?q=burton&tbm=isch)
