Fitbit - Unsubscribe Message

Default Web Browser - Button labels set context

Let's all take a moment to admire how nice these button labels are. 
The standard Yes/No or Ok/Cancel button groups place a higher interaction cost on the user. 

This button group, instead, provides great benefit to the user by removing all burden of interpretation.
