“Neither Netgate's responses, FreeBSD Core's, nor the off-record responses we heard from independent FreeBSD community members lead us to believe that there was in fact any process in place that could reasonably have been expected to catch this issue prior to it going out into the world in 13.0-RELEASE”

But it would help if he made it clear why he felt this criticism was specific to FreeBSD release13. It sounds to a naive reader like a critique that could apply to much of open source software. The author didn’t say that, but it’s a reasonable extrapolation to make.
