I did not attend the talk, I only leafed through the slides (thanks for posting 
the link!), so my impression is likely colored by that. I wouldn’t hold my 
breath for an «official» response.

That said, this all reminds me of several earlier talks and rants where the 
speaker seems to be unaware that OpenBSD commonly has been the first to 
implement a security feature as *the default* and in a way that it would be 
extremely hard to disable without a system rebuild, likely breaking seemingly 
unrelated bits in the process. If you look closer, a lot of the firsts listed 
more often than not are «feature introduced as a non-default option».

As to the lack of «public» review, keep in mind that OpenBSD was the first to 
make its version control (cvs then, cvs still) world-readable and visible in 
real time. At the time the normal mode of operation for open source projects 
was occasional release tarballs thrown over the wall with almost complete 
silence between. For public discussion of code, OpenBSD has tech@. Private 
mailing lists exist (invite-only, developer-only) as far as I am aware mainly 
used for discussions that would benefit from being out of the public eye for 
now.

Slide 43 has me thinking this person can not actually have been reading tech@ 
much at all, and the note about «systematic security engineering» subjectively 
reminds me of several earlier similar posts about OpenBSD practices not 
following to the letter somebody’s favorite «formal verification» model or what 
the buzzword du jour turns out to be.

That said, even OpenBSD probably has areas with potential for improvement, I’m 
just not all that convinced the presenter has actually been looking in the 
right places.

Slides for my sometimes-repeated propaganda piece (now probably in need of 
refreshing here and there) at https://home.nuug.no/~peter/openbsd_and_you/ 
<https://home.nuug.no/~peter/openbsd_and_you/> contains links to relevant 
material, at least. Please feel free to refer there or directly to the material 
itself.

All the best,
Peter
