The data seems to be well anonymized and aggregated and with a 4-week delay, so I don&#x27;t think I would object to this.<p>A related article linked at the bottom, <i>London garden bridge users to have mobile phone signals tracked</i> ( <a href="http:&#x2F;&#x2F;www.theguardian.com&#x2F;uk-news&#x2F;2015&#x2F;nov&#x2F;06&#x2F;garden-bridge-mobile-phone-signals-tracking-london" rel="nofollow">http:&#x2F;&#x2F;www.theguardian.com&#x2F;uk-news&#x2F;2015&#x2F;nov&#x2F;06&#x2F;garden-bridge...</a> ), signals something more troubling, as people there will be tracked individually and real-time.
