I understand that - my question is whether the name is actually a factor that contributed to the spread. As AfroThundr said above, people just want to get to their content and want the dialog to go away.
A known contact sends you a document - you're going to trust that and want to see the document.
Unless it said the app name was "I'm going to hack your bank account" they'll probably click it (and even then, some would go for it anyway.)
The message was "Google Docs would like to 'Read, send, delete, and mange your email'".
People are way more likely to accept that than if the dialog had been "hhhhhhhhhhh@mailinator.com would like to 'Read, send, delete, and mange your email'".
