Tangentially related, for those using MacOS and who have upgraded to Mojave 10.14.1, you might want to consider killing Apple’s News app. If you use the app, I suspect it tracks what you read as news sources. Even if you don’t use it, that itself is a metric.
However, by default you can’t just right-click delete the app. Apple in its wisdom has made the app nuke-proof even using sudo and terminal. You can, however, still eradicate it by booting into Recovery mode and switching off SIP.
