My guess would be that Ping wants to move anyway and this is just a way to do so and vilify the pot dispensary. If Ping just up and moved because of a few strip clubs or whatever, people could spin it the other way that they gave up on the community. This way, Ping looks like the victim, even though they were going to move regardless.
In 2011, I can't believe we are still acting like weed is a big deal.
