It doesn't come off as snobby or even pretentious, merely facile. The author has publications in distributed systems in reputed journals, is currently researching and teaching on distributed systems, and has worked with the Scala community for quite some time so at the very least she is competent and knows the subject.

If you want people to take you seriously, please try to be more precise in your criticism.
