Here's my take as a person with two linguistics degrees, one of which had a big computational focus on historical change:
The person who constructed the languages eschewed using the literary influences because he didn't believe that the phonemic inventory would be consistent over tens of thousands of years due to prior information that we have about diachronic change in language families.
What he fails to take into account is the fact that the wide availability of audiovisual distribution of language has a conservational effect that we've not really seen before. So for instance, while there is a large variety of English dialects in the US, "Broadcast English" and "General American" are quite stable and broadly available.
What they've done with the constructed languages of Dune would be like if they made a new Clockwork Orange movie without any of the Nadsat dialect. It robs something from the original text, all so a hobbyist can make something internally consistent that he's personally satisfied with and that may be marketed to future consumers. That sucks.
