Seriously. His reasoning is "it's not monolithic, this one package has 70 binaries that do different things, therefore it is modular." Clearly, his understanding of the word "monolithic" is as poor as his understanding of UNIX.
Coreutils has a lot of binaries that do different things. Is is monolithic? The GNU ecosystem and autotools barely function without other GNU tools which aren't part of the same project. Are those monolithic? Monolithic is a canard.
