I don't understand how the OpenBSD project defines "free", so I can't usefully comment on how they consider the Apache license "non-free".
It sounds from https://softwareengineering.stackexchange.com/questions/2632... like they are reading the existence of an explicit patent clause in the Apache license (regardless of what that clause is!) as an "additional restriction". I want to know whether they believe the MIT license has a patent grant, and if not, what they think "Permission to use" means.
