To use a Fitbit, you need a Google account (unless you have a legacy Fitbit

Google account, which installs the Google account centrally on the phone,
which means that account infests the rest of the OS and gets used for other
stuff (eg Play Services/Store).

 
  Are you sure about that? Can't you just use a Google account to login
into the *app*, instead of into the *system*/OS? Many apps have such
functionality, i.e. an app-specific login, so I wouldn't know why the
Fitbit app would be any different.

It shows under Settings -> Accounts, and the Play Store uses it without
asking.  There's no way to sign out of it apart from deleting it from the
phone.  If I do that the Fitbit app stops working and wants a sign in again.
