The situations are indeed different because it's FreeBSD and not Linux. And there's different history behind their /dev/random implementations. But the underling concern is the same: a lack of trust for rdrand -- and the solution should be the same: to only ever use rdrand as an "improver" and never as an actual source of entropy.

The difference is that Linux already didn't trust RdRand, and didn't use RdRand as the sole input to /dev/random.

You're right, the OP's post was badly worded, possibly mistaken, as it implies that the change Linus refused to make was analogous to this change.
