I'm making an assumption here since it's been a while since I've looked at SEO, but I'd assume that page rank in this case matters. Any friction at all leads to fewer conversions, which means fewer sales for Dropbox. If a less knowledgeable user downloads the Apple app instead of Dropbox in this case, there will be some portion that don't end up installing Dropbox and they may instead find their way to icloud when recommended to install it after installing files. There is no way to tell the actual impact, but I don't see how it could possibly have caused no impact. They control the market, they have a responsibility to maintain a non-amazon like image. Hopefully it was a mistake.
