Trackers
Believe it or not, some stores sympathise with you. They might actually be run by people like you, people who read your story.They still want to know how you proceed round the store, because that helps them optimise shelf layout, identify hard-to-find items, and so on. So yes, they might use the standard in-store CCTV to observe your journeys, and when they figure that you and people like you always have difficulty finding the eggs (seriously - why is it always so hard to find the eggs?), they'll move the eggs somewhere more prominent, so they can sell more eggs and you can buy what you came to buy.But that's as far as it goes. They don't follow you out the store, let alone into your bedroom. They don't match anything with third-party data, let alone your mobile phone number. The store just wants to know where to put the eggs.Unfortunately, your bouncers have simply been told to "hurt them if you have to, I’ve really had enough of it". So last time they came in, they smashed the CCTV cameras. The store-owner remonstrated with them a bit but the whole debate around bouncers has become so polarised that there was really no point arguing.---And if this metaphor seems a little obscure, this is why it is irresponsible, populist and ultimately self-defeating for uBlock and chums to block self-hosted Piwik and other such internal analytics tools. Because some of us are trying to do the right thing and your bouncers are still beating us up.
