I hate the fact that Apple kept asking me to accept the terms of service for Itunes. I have no intention of using Itunes. I would remove Itunes and many other Apple Crapware from my computer if I could.
Why did you install iTunes in the first place? It’s an optional download and doesn’t come pre-installed. To remove iTunes, drag it’s icon in the Applications folder to the recycling bin.
In fact iTunes no longer exists in the last two macOS releases. It was split into the videos and music apps and the iOS recovery stuff was moved to finder. iTunes now only exists on Windows.
The iTunes store still exists though. Which is probably what the agreement stuff was for.
I haven’t tried it but I’d be surprised if you couldn’t delete any stock application. I’d try doing it through terminal and then as sudo or without SIP if that didn’t work. But this post describes a straightforward way:
Install Little Snitch, and disable the built in allow rules for all of the Apple and iCloud stuff.
Each time an Apple process tries to connect, make a rule that says that app is never allowed to connect to any server, and set the rule lifetime to "forever". There are about 20-30 Apple processes in macOS that phone home even if you don't use iCloud, iMessage, or FaceTime, or the App Store. Once you block all of them your computer will be quiet on the network.
