You might recognize Kai from the tech-workers field-for-rent confrontation from last Summer:

Gentrification in the Mission enabled by the SF Parks & Rec in collusion with the private City Fields Foundation. Without community approval, the private foundation decided to issue costly permits to a small traditional pick-up soccer field. The AirBnb vs. Dropbox players show up and try to kick the neighborhood kids off of the field at prime time without even showing their “permit.” They don’t want to wait their turn and play with everyone else. They finally agree to play all together but then the guy with the permit arrives late. “Don’t you understand? You have to leave ….. we’re part of the community, this is awkward and weird, disastrously weird” Off camera, the other guy remarks “Who cares about the neighborhood?”
