I would disagree, or rather: it depends. You can print the --help of bash, but will that actually tell you anything about bash except a really superficial subset of flags? In the same way that the author argues that the help of his tool is too long to be useful, the help of bash is to short for the same reason. He argues that "cloud tools have a gazillion options where UNIX tools have good defaults". Bash has a gazillion options and no good defaults. As a matter of fact, bash on defaults is fairly dangerous. Yet, it is at the heart of most Unix systems today I'd argue.
