Declared by publisher means the switches come straight from the winget manifest the publisher (or community maintainer) submitted to microsoft/winget-pkgs.
Default for {type} means the manifest doesn't specify silent switches, so the framework's standard switches are shown (e.g. /S for NSIS, /quiet /norestart for MSI).
