I still don't buy it. Could be the same in saying Apple offered $1 Billion for an app on the App Store. It rarely happens but it happens. Then everyone saying "no, this isn't Apple, it's a fake". Then someone else gets bought for $1 Billion and the original company loses out on a deal of a lifetime.
This is a terrible analogy.
The difference is that if any company, Apple, Google, Facebook, Amazon, drops a billion dollars on an app, they aren't doing it via casual channels. No one gets a single phone call or a friend of a friend sending an email offering that kind of money. When a business deal like that occurs, their lawyers call the software developer's lawyers.
