When I look at Grafana here: https://grafana.com/legal/privacy-policy/

it says:

No uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online.

and we not only know that this is some utter bullshit but also speaks volumes about the CEO and makes me wonder if they read what the courts just told scumbag LinkedIn?
