It turns out the wine is from a nearby vineyard not at Orange House. The connection is that the person running this vineyard is a former member who used to run the Orange House vineyard before he left.
The allegation that the person is a "Former Member" is a valid point to contest. Announcing leaving the cult after a scandal is a good sign, moving to a new winery nearby is pretty neutral, still receiving hundreds of thousands in orders from the cult members is a bad sign. On the balance, probably not enough to convict in a court of law, more than enough for Google to take their own investigation before deciding if they see it as self-dealing.
