I guess it's semantics. Red Hat (and others) paid Microsoft the $99 one-time fee to have their PE binaries signed with a Verisign certificate. Shim is used to intercept the boot loader, pass the certificate check with the signed binaries, then execute the boot loader which may or may not load a signed kernel. I call that a hack since there's no way to open source a signed binary and Windows can just boot straight from its boot loader without jumping through any hoops.
