Ok so they split and copy all the packets, nobody else is concerned with the complexity of tagging, filtering, rebuilding and contextualizing this conceptual volume of packet data?
Beam splitters are not enough, they would need something to interpret this traffic.
Then you just process basic metadata. Size, IP source, destination, timing, and statistical analysis of the binary. Assuming that they have ways of converting IP to an identity that information alone would be hugely revealing. In fact basic metadata is what they have admitted to recording.

Something is missing here.
