My next door neighbors kept a hive, and my concern was whether or not they were knowledgable - they also kept a rooster, whole 'nother story. My neighborhood is considered "in town" *now*, but prior to any housing development in the 50's it was zoned to allow livestock, and that zoning has not been changed, perhaps in part due to a small, but commercial equestrian center nearby.
If neighbors are taking care of whatever activities they are legally allowed to pursue, and they don't present significant risk, or intrusion of enjoyment of other's property - good, though noting that zoning allowances don't always keep up with changes in the general character and use of any area.
In the linked case, I, too have mixed feelings. I agree that bee-keeping, by knowledgable and diligent folks is usually an environmental plus, and folks with allergies or other like considerations for naturally occurring elements of the environment need to manage a risk that can be present with or without someone's purposeful introduction of bees or the like. But, if I had such an allergy, I would also pursue legal means to limit the addition of risk to me, in the present case by attending any hearings and requesting that bee-keeping not be allowed. If a governing body chooses to allow it, I would seek to meet with any bee-keeping neighbor to see what, if any, considerations could be made, regarding hive location and care, and work to understand particulars of bee-keeping and how to mitigate my own risk.
I can't help but wonder how "butterfly poop" lady would address the matter.
