I think that's actually worse. It's several disparate teams failing in similar ways. It makes Amazon looknfoolosh with their hiring process and "principles".
No one involved trusts Amazon to actually employ them 2 years from now, thus Amazonians have an extremely short-term mindset.
It's not like they can't look across the lake to Bellevue and see Nintendo, Microsoft, Valve and others delivering consistently. The Amazon culture is just too toxic to allow this to actually grow into a popular product.
