1. I think security and privacy has a lot to do with it. If the services interoperate then other companies that make the services will get access to your personal data even if you don't use them. 2. Even though there are so many services, I find functionality to be lacking on many of them. I don't want to use facebook, because of privacy. I don't like signal because it doesn't give you your chat history across devices. I used to love hangouts, but google destroyed it. Many of the services are tied to your phone and don't work if it isn't on. There is a good chart in german comparing the different features. I just use imessage because it's end to end encrypted, i trust apple's privacy and it works.
