Well, I’m sure the demand for recreational marijuana is much larger than the demand for cigars. And since Apple is always looking for revenue... it would only make sense to cater to cannabis.
It come down to a business Apple, allows Apps in their App Store that they like, and barring ones they dislike.
Apply is not big apprently to helping people find Cigar Stores, and Lounges.
Like a business that post a sign , "We Reserve the Right to Refuse Service".
We as Cigar smokers can boycott Apple Products if we choose.
