Of course, all your points are valid. However, if I purchase a new phone, I want a new phone. I don't want to get a white box replacement on the same day my phone arrived and have it no longer match the fancy retail box. If my phone comes bad out of the box, I want another new one, but I'm probably in the very tiny minority on that.
And I absolutely get your point in regards to forcing us towards mobile share eplans and NEXT installment plans. That makes sense, and the "out" is for them to still offer the 2 year upgrades themselves, tucked away on their own website.
For me personally it doesn't matter what kind of box it comes out off or if the serial won't match my original box once I get it replaced.
All it matters is if it functions correct.
I'm not ocd picky with yellow screens, blue screens or other nonsense some people stress about
