This is a temporary situation: we should display this icon only in location which are actually Google-free.
About all the other location, we can (what comes simpler)
make a colored circlet
put an icon
put a selected icon among few, which express the amount of trackers present in the website
I would suggest to start with the 1, but if @bnvk has a suggestion, considering years ago worked on icon-set, let us know!
