I'm not sure I understand your complaint/concern. We're talking about text chat and video chat clients, and you're concerned with giving them access to your contacts? How are you going to contact your contacts with the apps if they don't know who your contacts are?

All communication apps are going to require access to your contacts so that your contact information can be used to communicate with your contacts. Duo and Allo are tied to phone numbers. They use phone numbers to identify users, so without access to phone numbers (contacts), they can't function. This is the same as all text message (SMS) clients, and the same way that many other chat clients work (Signal, WhatsApp, etc.).
