It's not even funny:
$ ll /nix/store/*-insect-5.9.0/lib/node_modules/insect/node_modules/clipboardy/fallbacks/*
/nix/store/…-insect-5.9.0/lib/node_modules/insect/node_modules/clipboardy/fallbacks/linux:

.r-xr-xr-x 331k root 1 Jan 1970 clipboard_x86_64.exe
(clipboardy ships executables and none of them can be run on NixOS btw)
