Anybody could win this thing. You didn't even need to download an app.
It's like drawing a number out of a huge hat.
I thought this was sorted when the contest was announced.
THE WINNER IS THE PERSON THAT DOWNLOAD THE APP AFTER THE 999,999,999 APP WAS DOWNLOADED OR THE PERSON THAT SUBMITTED THE NON-PURCHASE FORM AFTER THE 999,999,999 APP WAS DOWNLOADED
No lucky draw. The winner had to be the 1 B person to download an app or submit the form after the 999,999,999th app was downloaded.
Please don't try to argue, this is the way it is stated in the rules, and any other statement is ignorant.
