Sam Altman has already stated what Peter is allowed to say (and presumably think) as a condition of his continued association with YC. There was a recent spate of articles by and about Sam Altman, including a probing interview by his brother (presumably in lieu of a blatantly self-serving monologue by the subject). So we kind of know Sam's viewpoint and his tendency toward defining who can say and do what at YC and on HN. I would call that shameful in a public commons, but this is a private enterprise, and Sam is free to set the boundaries in Sam's world.
