Honest question, how do these companies use OpenBSD? I can totally understand the security benefits of OpenBSD, but it's also my understanding that it's very "unstable", in the sense that they constantly introduce breaking changes. So I don't understand which company would put their "extra-secure" data in such system.
It would be nice to see the process behind this, it's hard enough to convince a company to donate $100 let alone sponsor a conference or a project.
