As for "some truth," what is it you find not to be true?
It isn't that anything was outright false, just that it painted all people and processes in government with the same brush. My experience hasn't been nearly so monochromatic.
Another way to look at it is that your note is a useful primer for applying for any job with a large bureaucracy. That bureaucracy doesn't have to be the government. I've seen the kinds of behaviors that you warn about in every large, process driven company I've ever worked with as well.
