I don't know why it's so hard to find.
Most restaurant hash brown are not very good. Just not that flavorful, not that well cooked.
The only good ones that come to mind outside individual restaurants are at Waffle House.
Even some decent independent diners can't do them.
I guess that leaves 'cook them yourself' dealing with the oil and hassle.
And no I'm not counting things like the patties at fast food.
