> this allows for anyone to track the content viewing history of IPs

Is that worse than only Google being able to do it?

Considering that Google is a subset of anyone, I have to assume that it is.

If you consider Google being able to track something as a negative, then Google+n would be at last +n negative.

Also tracking the viewing history of an IP is not that easy. People trying to do this can be easily spotted by the trackers.
