I always prefer innocent explanations, but in this case it's hard. They created an additional account. Okay, you could say they did that (as they say) for debugging purposes. But if it's only for debugging, why did they add extra code to hide the account? That's hardly explainable. The most "innocent" explanation is that they wanted to have a way to do support on these devices without the user being aware of that. That's bad enough and definitely lying to their users.
