mojotoad beat me to the punch. I would not want to be employed at a company that worries how my personal interest in my craft may impact my work output. I'm not looking for a place that is looking to hire a drone. This is along the lines of Abigail's Oath - I'm hired because I know what I do, not because I do what I'm told.
Bottom line, negative as it may seem that it prevented you from getting this job, it probably prevented you from getting a job you didn't actually want to score in the first place. And esp. if you already had more interviews in the pipe and could afford to pick, I don't see any reason to think of that in a negative way.
