Did Mark Zuckerberg's yacht ignore requests for help?

linuxbert writes: a 21 foot boat required assistance in Alaskan waters. The closest vessel to it was Mark Zuckerbergs yacht Launchpad, but they ignored the request, claiming the yachts radio was on another channel. They slowed down, and let a cruise ship respond, departing after the assistance was provided.

Zucks other yacht, wingman was also in the area, and sailed past.
