As for the "If you rely on machines like this, I am truly sorry" - I don't really blame her. She says she's sorry because she was trying to administer a system that a. has vulnerable software she couldn't easily upgrade or even remove, and b. some of the common utilities that she uses to troubleshoot Unix systems just don't work and this makes a competent Unix admin's life harder than it needs to be.
And Rachel, by all accounts, is a very competent - no, scratch that - talented administrator. So she feels the pain of not being able to use commonly available tools and not being able to keep systems as secure as she would like.
If you feel offended by this, then it seems to me you are actively looking to be offended and you have your own agenda.
