Sad, but understandable. "OpenBSD writes their own ROFF interpreter" isn't very interesting, but "OpenBSD purges C++ from core" appeals to developers' strong emotional responses toward C++.
Yes. And it's not so much a C++ purge as it is a "unmaintainable GPL-licensed slow software" purge, as far as I understand. C++ does hurt comprehension, but it's not the main complaint.
