Some person doesn't like Snapchat. Their dislike of Snapchat and inability to install it on their phone due to choice of platform has absolutely nothing to do with, and absolutely no influence on what phones other people buy or what apps they install on it.

I have an Android phone and it doesn't have Snapchat on it. I also have friends with varieties of phones, and Snapchat, and they're very intelligent. It's donwvoted because it's a pointless "get off my lawn comment" that says nothing other than "I look down on all Snapchat users".

It's unlikely that the absence of snapchat on Windows phone will improve literacy.
