Since it isn't very anonymous and doesn't likely have any clear tax advantage, I think the mostly likely reason for the trust is just to avoid probate in California if he passes away. https://www.nolo.com/legal-encyclopedia/california-avoiding-....

Indeed. It's quite common to move your assets to a living trust in California for this reason, even for the only somewhat wealthy. It's basically SOP to set up a trust rather than just a will if you have assets above the simplified probate threshold. (I'm sure Moskovitz, being more than somewhat wealthy, has additional reasons.)
