Your apps have no permissions until you allow them. If you install spyware and it wants all your contacts and files it has to ask. You simply select "no" and then remove it.
Apps would force you to consent to eg contact permissions "in case you want to share something to a contact" and then harvest all your contacts. Apps can no longer use that pretense.
