The advertising industry doesn't just want to know that there
are 100.000 people interested in some product, and which traits
these people have in common. They want to serve each of them 
targeted ads. You are are right that for that they don't need
to identify people by name, but that's besides the point.

Privacy is much more than not being identified. It also means
that others are not able to exploit knowledge about you that
has not been given explicitly for some particular purpose.

Practice shows (in particular in the US) that when the possibility
to exploit such knowledge exists, it will be used. Today you can
be refused a job because Amazon and/or Google know what you are
reading and has sold this info to some employment screening agency.

Apart from that, it's quite easy to identify people by combining
'anonynous' data. See some of the references below.


Bruce Schneier is regarded as one of the most authoritative
experts on security and privacy related matters. All the
links above are from his blog. You can question my or other
poster's knowledge, but probbaly not his.


A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
