You've put into words what I've been internally struggling to voice. Information (on the web) is a gas, it expands once it escapes.
In limited, closed systems, it may not escape, but all it takes is one bad (or hacked) actor and the privacy of it is gone.
In a way, we used to be "protected" because it was "too big" to process, store, or access "everything".
Now, especially with an economic incentive to vacuum literally all digital information, and many works being "digital first" (even a word processor vs a typewriter, or a PDF that is sent to a printer instead of lithograph metal plates)... is this the information Armageddon?
