In case anyone is curious and doesn't know, "Do Not Track" was originally a proposed Internet standard from 2009-2018, but was never formally adopted by the W3C. Its successor is called Global Privacy Control (https://iapp.org/news/a/is-gpc-the-new-do-not-track/). I'm guessing that Grafana is playing games by saying there is no technology standard for DNT, because technically the new standard has a different name. I wouldn't consider a company that plays semantic games like this to be trustworthy when it comes to privacy.
