No, that's not what it means. To quote a couple of places from Judy's article:
"The bottom line here is that there isn’t a hint in the decision that the copyrights of all photographers whose work appears online is at risk. This decision is — like all fair use decisions — based on its unique individual set of facts. This particular combination of facts isn’t likely to be repeated in any other case — which means it can’t be used to predict the outcome of any other case."
and:
"copying of photos found on the internet is not fair use, not in all cases, not under all circumstances."
