That URL provides no support for your claim at all, and OpenBSD isn't even mentioned. Sadly, a moderate amount of Googling has turned up nothing about why OpenBSD doesn't allow the Apache License: all dead ends. The only thing that turns up is "well, we don't like it philosophically".

Apache is very well regarded as a BSD-style license in the commercial environment.
