I’ve noticed this tactic more and more. Price a product as if it’s yours, but then disown it when inconvenient.
I can’t imagine Apple saying something like “that’s a Samsung issue, take it up with them” because of a component.
As a customer, I don’t want to have a decoder ring for how to get support for my product. If it says google and is sold by google then google should fix it. Maybe they sub it out to HTC or Huawei or whatever, but don’t make me know about it.
If google makes bad supply chain decisions then own up to it. Not doing so just makes Google seem incompetent at management as I don’t care or have any value in them directly for manufacturing.
