Not knowing the influences that led to how things got to where they are in the specific example, I can't really comment further.
In general, if the DM has preferences then in theory s/he'll recruit players who in general go along with those preferences. That said, I believe it's the DM's role to design-curate-determine the setting and what it in it, and then to neutrally stand back, leave it to the players to play their characters in that setting however they so desire, and have the setting react in somewhat-reasonable ways to (i.e. introduce consequences for) what the characters do.
