Not necessarily a problem. I was in a hotel recently that doesn't secure their network. Easily 80% of the devices in there were Apple devices. The next most common device was Samsung.
The people spending $250/night at the particular urban center hotel made the choice that I observed on that one occasion. If that's a trend vs. a datapoint, it could be very meaningful for somebody trying to sell products.
Personally, the next time I find myself in a cheap roadside place, I'm going to make a similar comparison.
