> Quad9 is based in Switzerland. Despite what may be common knowledge from movies, there is a very formal and rigorous process for governments (Swiss or non-Swiss) to demand data.

Due to Lugano Convention [0] / Budapest Convention [1] / Hague Convention etc, I don't see how Switzerland is any more insulated than, say, Norway is (both these countries are part of EFTA & signatories to various UN/EU/EFTA treaties). Per this article [2], Switzerland ranks below Ireland, Portugal, Denmark, France in Data privacy laws (in fact, it ranks the same as the UK).

If I am being honest, at this point, "based in Switzerland" (or Cyprus or Sweden or Gibraltar) comes across as marketing gimmick VPN companies are notorious for.
