So why should iMessage get all of your contacts by default?

I made the choice for Apple to have my contacts by buying an iPhone. If I didn't want Apple to have my contacts (as I do not want Google or Facebook to have mine) I would have not bought an iPhone.

Personally, I made the choice for Apple NOT to have my contacts (by entirely disabling iCloud). The only company I accept handling my contacts is the one I paid (Fastmail).

Apple doesn’t get all your contacts.

Your local Apple device has a messaging app (iMessage) that can see all the contacts on it.

iCloud puts contacts on Apple servers.
