federation allows different servers. Some might be more private than others, and federation allows people to choose the flavor they want.

Remember it is not just public posts which you should be concerned about...but it is your interaction with the sever as well, as well as your semi-private communication.

Do you really have meaningful control though? If I trust server A and my friend trusts server B and I publish posts for my friend to see, now I just also trust server B, right?
