There are also some reasons why not to cc: to person when replying to list. I prefer to receive msgs in list order. Generally, mailing lists do not have the highest priority in a work day, thus I read/reply when I have time (like now at 01:20 I should be in bed...). Duplicate removal removes the copy received later, which is generally the list one, but I prefer to keep the list msg. A lag of a few minutes - oh wow, can't handle that :) Plus I so far didn't spend the time setting up duplicate removal. As I get my copy from the list, I can't see any useful reason why I'd want another one.
Of course, if someone requests to be cc:ed I do that, this is often the case for developers' lists where someone wants to report a bug and catch the answers but doesn't want to subscribe to the often high-volume list itself.
