The fact you haven't heard that outrage simply suggests that you haven't been a network operator before. We have an RFC, in fact, that addresses this very point.
https://www.rfc-editor.org/rfc/rfc1925
Note truth number 4:
> (4) Some things in life can never be fully appreciated nor understood unless experienced firsthand. Some things in networking can never be fully understood by someone who neither builds commercial networking equipment nor runs an operational network.
Most people have not ever wrestled with operating a network. To get outraged about the exploitation of user activity/metadata and violation of end user trust perpetrated by today's network operators, you have to have wrestled with having at least tried to operate or build out one yourself.
Only once you have (and it doesn't take many) multiple users completely dependent on you as a single point of failure or as a vector for intrusion into their intimate affairs, will you truly appreciate the burning white anger the more ethical of us feel at the behavior of the largest network operators.
In fact, policymakers and law enforcement have all but weaponized that fact. Usually couching any further abrogation or unraveling of end user expectation of privacy under the guise of "keeping you safe" or "protecting the children" (which a vast majority experience first hand), without at the same time pointing out that "oh, hey, this means we basically get to intrude on all activity you conduct over a network".
Which nowadays is "all activity you conduct with someone else that doesn't involve meeting face to face"
Which is a lot.
Think about that long and hard.
