There is a drawback with using adblockers in that it is not as trivial to notice if a site is hostile. It is about the only reason to not use it I can imagine.
uBlock Origin does show a little badge indicating how many resources it blocked on the current page. NYT shows a 9 for me right now, HN doesn't show any number at all, FoxNews shows ~30 but keeps growing every 2-3 seconds.
