How many users block Google analytics? (2017)
One of the corollaries to this is that if you are basing your decisions on analytics, you are probably under-representing people who block them, who often tend to be a non-representative subset of your users. I have seen multiple projects do things like stop supporting features that their analytics “showed nobody was using” but failed to realize that a significant portion of their (often technical and very vocal) userbase did in fact use the feature.Oh, and by the way, responding to these kinds of issues with “if you wanted your voice to be heard, you should have turned on analytics” is inexcusable.
