Rule #1 when working with/on a platform: Transform customers to your own platform. Do it in a way that does not violate the AUP of the platform but do everything you can to „own“ the customer contact. Never become dependent of a single platform that temporarily may work in your interest.
This rule is somewhat universal and matches all business types and platforms: Amazon, eBay, AirBnB, Uber, YouTube, App Stores.
