How have they responded?
Do any of these issues make the bike unridable?
They offered to repair it for 20USD if I would ship it back to them. Shipping would cost me something like $800 though so no real point. They weren't prepared to offer any other solution.
The bearing paint is just lazy and has no influence on ridability. The headtube crack? Possibly ridable as it is but equally could be very unsafe. It's hard to tell.
That does look like it might have been dropped on the top corner... I wouldn't rule out shipping damage. Never hurts to try and get the shipper to pay... but ultimately you should be able to repair that fairly easy. I would be interested to know how they handle the situation.. discounted from triangle in case you didn't want to bother with repair, etc...
The box was fine, certainly not crushed in any such way as to cause this. I've personally cut up a whole bunch of crash and impact damaged frames. This doesn't resemble any of the damage patterns you typically see in those situations. I guess it could have been dropped on the top corner before it was boxed..... which broke it along the massive manufacturing flaw.
