No doubt there is a massive amount of information that can be gathered
from in-box telemetry. This thread appears to be more focused on
providers gathering data from traffic in flight across their
infrastructure.
Yeah, my curiosity was whether ISP were trying to get in the monetizing
traffic analysis biz which seems to be a small degree but they can't
really compete with the much finer grained information that other means
can provide and that they have no particular expertise in it or an
institutional desire. For things like Google and Facebook, that kind of
analysis was part of their initial business plan.

hashed DNS lookups just to be avoided.
