Intel cooperates with organizations that obey embargoes and don't badmouth their partners in public, like Red Hat, Canonical, and probably the Linux Foundation. Intel does not cooperate with OpenBSD.
Note that I wrote and included a suggested diff for OpenBSD already, and that
at the time the tentative disclosure deadline was around the end of August. As
a compromise, I allowed them to silently patch the vulnerability.
Regardless of whether it is, you should expect the result of that to be that nobody trusts them with embargoes.
Which is in fact, what has happened.
Google broke an embargo early. https://security.googleblog.com/2018/01/todays-cpu-vulnerabi...
EFail embargo was broken. See https://twitter.com/seecurity/status/995964977461776385 and http://flaked.sockpuppet.org/2018/05/16/a-unified-timeline.h...
I don't think picking on OpenBSD is the right thing here.
a.k.a. truth
Linus has "badmouthed" Intel in much harsher and more explicit terms. Linux is just too big for them to get away with trying to smear and slander so they ignore him and move on.
