I disabled Apple Push Notification Service but it's still attempting to connect to Apple servers

I disabled the service as per the instructions on this page: How to disable Apple Push Notification Service (apsd) on OS X 10.8?

Yet this service is still running at startup!

How do I disable it once and for all?

Edit: I'm using Mojave


Found this googling around:

If you don't use FaceTime, put this in a Terminal window to get rid of apsd permanently: "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.apsd.plist"

This will unload apsd from launchctl (the process that launches it at startup), but you'll still need to kill now.
