Even if they maintain algorithmwise exceptions list and not a masterlist of whitelisted sites, they might still include the whitelisted sites in all those exceptions list.
Panda update is exposing these whitelisted sites (or sites that figure in most exceptions list) more clearly now.
If someone thinks that whatever these top rated sites do is nothing wrong (as they still rank on top) and try to do the same to their sites, they will be shooting themselves down.
By maintaining these exception lists and floating them on top, google is setting bad examples for others.Sure, these sites may be good and useful to the readers but most things they do to remain on top may not be good examples for others to follow.
