This installer and the relationship between DetSys and Nix has also been subject to major criticism about conflict of interest between community interests and DetSys, since everyone agrees the official Nix installer has major issues. "Determinate Nix" (as DetSys calls the nix configured with their installer) also enables features that are the de-facto way to use Nix these days, but are disabled in the default distribution because of... let's say... commitment issues.

If you want a community run alternative, try Lix. They have a version of the DetSys installer too - and they actually cut releases of nix instead of building moats around it.
