I had forgotten I was running Ublock origin / Privacy Badger / Ghostry so I was a bit confused with the results from that site.
I think it is Ghostry that is faking the responses but I still have a pretty unique fingerprint according to https://coveryourtracks.eff.org/kcarter?aat=1
As near as I can tell, it’s always been owned by Cliqz, who produced some privacy-focused browsers (named Dawn or Lumen) and a search engine (Tailcat) that was ultimately purchased by Brave. The whole thing is majority owned by a German media group, Hubert Burda Media, and while its missions towards increased privacy seem to be sincere, I don’t know if I’d trust them implicitly.
All that said, the main project looks to be open sourced under a GPL3 license, so distrust and verify: https://github.com/ghostery
Isn't ghostry compromised? Having been bought out by an ad company?
