Follow the money.

Partners at VC funds are employed (funded) by limited partners (LPs). LPs are typically institutional cash and tend to be conservative. A26Z's LPs and potential LPs would not be pleased if they saw a video of Ben giving a talk wearing his "No Bitch Ass Ness" t-shirt.

Not so much. Have you read many of Ben's Blog articles or spent much time with Ben in person? If you had, a "No Bitch Ass Ness" t-shirt would be considered entirely appropriate dress for Ben. My guess is that he just instinctively is conservative about cameras, and being recorded. Probably the result of all the discovery he's gone through over the years as an executive and CEO at various companies.
