This is the reason I made a dummy contact of myself. My own contact is by far the most bespoke in my address book: it has multiple numbers, emails and addresses. It also has many "family member" fields filled out (which allows Siri to understand things like "call my youngest sister" or "when is my uncle's birthday"). Apps I don't trust only get the dummy version of me, which just has my spare phone number. But I guess it would be unwieldy to do this for other people as well.
