Why are Pixel phones allowed to be sold then? Google broke emergency calling on a least three different models, and at least once across models.

In my country, only cell phones certified by the government telecommunications agency (Anatel) can be imported, so I can't for instance go to the Jolla or PinePhone store and buy a Linux-based smartphone; if I tried, it would be sent back the moment the package entered the country.
