> You bought a Google phone

Wileyfox make their own phones and Android rom. It's not really a Google phone (it may have Google Play Services, but that's different).

The third party dialler app in this case was not provided by the ROM maker, but by a third party who gathers tracking data from usage of the dialler app. The ROM maker disabled/removed the stock dialler app from their ROM.

If it was an opt in feature, then I believe OP would be happy with that.
