Consumer products are demand-driven. This is like saying my shrimp-flavored cola is failing because I don’t have distribution deals.
Pixel is great hardware, but Google has failed to generate enough demand for consumers to be going into stores and the n leaving because Pixel isn’t sold there. That’s what gets distribution in the long run.
Pixel phones have lots of geoblocked features. For example, they lose most of their 5G/VoLTE/VoWifi abilities if you use a sim from a phone network in an unsupported country, even though other models of phone don't have that issue.
A bunch of other features are geoblocked in the EU, or geoblocked to the US and Canada only.
