A simple solution is to place signs at road crossings for feeds located up or down the road a few hundred yards, allowing those who want to attend do so without disrupting others who don't have an interest.
Hiker feeds however may be inevitable from an anthropology perspective. Its an evolutionary process commonly seen across the landscape of human history where trail intersections with predictable traffic patters attract service providers. These can be altruistic people offering food to food "with a message", eventually leading to commercial enterprise establishing itself on the trail or corridor. I am hoping this is not the case but history provides the lesson if we can learn from it.
