I'm calling non-event because everytime the Media reports these "Emerging Critical Threats" like the sky is falling, a month down the track nothing happens.
Maybe, at most 1000 people in china infect their device by manually enabling side-loading for pirated apps and the rest of the world gets on with life.
I'm suggesting its not sophisticated or unknown because it just asks for permission through the intended API, i.e Not A Bug. I didn't mention anything about how the user perceives the question, that completely out of scope. If I come to your house and ask to steal all of your stuff and you say "Yes" because you didn't understand the question, that still doesn't make it a sophisticated robbery, thats just a normal robbery. We'll call it a user misunderstanding shall then we?
