Firstly, they generally aren't storing everything, forever.  Most of the 
time, they feed into collection/analysis systems, and most if not all of 
the actual packets are discarded.

In many cases, they're only enabled on a situational basis - say, a 
security incident or a troubleshooting session.  Most if not all of the 
packets are discarded afterwards, in most cases.

In most cases, they're running on completely out-of-band management 
networks, using transparent taps or SPAN ports or equivalent.  In some 
cases, they can be used to intervene in the cryptostream - but even in 
that in-band case, all the management functions are still isolated on 
out-of-band management networks which are not interconnected with the 
production network, and are further isolated as necessary by 
implementing situationally-appropriate network access policies.

I guarantee you that your bank, your hospital, your insurance provider, 
your credit card processor, your retailer, and/or your government 
welfare agency are doing this, and have been doing it for a long time.

It's quite common in the national security space, as well as other 
governmental bureaux.

I'm not saying everyone has implemented this perfectly, or optimally - 
but it is a common practice which has been going on for many years, and 
the loss of the ability to perform these functions would result in a net 
security loss for these organizations and for their customers and 
constituents - i.e., proles like you and me.

It isn't new, it isn't unique, it isn't a case of a small group engaging 
in special pleading.  What's amazing is that very few engaged in this 
discussion seems to understand all this.
