Survey author here. We didn't have the time to correlate device/browser/etc. to other data points last year but we did use the location: https://2017.stateofjs

  Are you crazy? People buy data sets with browser statistics and location all the time, to augment other data sets that attempt cross-device user tracking. The more instances of browser fingerprints I have, the better I can tie you between different devices. I used to work for a company whose whole business model was essentially to buy data sets like this and normalize, join and aggregate them into much larger data products sold to third parties or queried in mobile SDKs. There are whole companies that exist just to collect and aggregate disparate data sets like this to make cross-device advertising measurement more possible. If you can only match 0.01% of the users in some ad campaign, then being able to even just double that fraction by also finding the same users on other devices is hugely valuable. The signature of your browser stats, location, and choice of what to browse absolutely can enable this matching, and a host of other techniques (like matching to similar users if no exact match is found, and using machine learning on huge sets of traffic data to learn how to perform the matching). It sounds like your lack of imagination is putting people at risk in a disturbing way to me.
