sadly there are a lot of people who will always have a gripe with this update. From what I can see they did a great job moving down a lot of poor quality/similar cheap type sites.
A lot of people who complain do not realize that there site just is not that great. People feel a certain entitlement to a SERP just because they have ranked there for so long, getting away with shoddy content and a poor spammy/paid backlink profile. Gone are those days and now are the days where unique, updated, fresh content is what works.
