wow I didn't know that!
I better stay on my toes, and to answer your question, no, I think they shouldnt but that's purely because it directly affects me if I fall behind.

Google has been making it difficult for low quality link building and low-quality content to count anymore.
Ezine for example suffered a lot after the panda update. In turn, Ezine has made it very difficult for its members old and new to upload low quality articles.
As they say- S;;T rolls downhill.
