I think the parent comment's point is that Firefox is worth celebrating because they're making this (and other changes) with no ulterior motive other than championing user privacy. But with Chrome, the user privacy improvement is a biproduct of Google making profit-oriented decisions, and not the focal point of their change. I'll happily celebrate Google making a privacy-oriented change that's actually intended and not a bi-product, but this isn't such a case.
