The pixel is advertised everywhere as a Google phone. Who makes it doesn't really come up in their product communication much.
And the 'flagship' label is literally in the title of the Pixel products on Amazon. And on the website it's called "Pixel, phone by Google".
> People buy a low end Android phone and hate the entire ecosystem because the phone performs like crap.
This seems like an antiquated view of Android. I don't think people see Apple as having a monopoly on luxury/quality devices anymore. And considering the heavy OS modifications made by different companies and the entire UX experience of dealing with a company (customer service, website, accessories, etc), I don't really see why it matters if your mom thinks she has a "Samsung" or an "LG". There's more to Android phones than the base OS.
