As did Linux before Git, but Linus and the core team around him were finding the process getting too cumbersome and bottlenecked. Linus "scratched the itch" and produced git both specifically to fill that set of needs and with the intention of it being generally useful for other projects they were concerned with.

OpenBSD's kernel development is presumably run differently (IIRC there is a much smaller number of people trying to directly feed into it for a start, which was a key problem with Linux at least at the time Git was birthed) so processes and tools that fit their needs will look different. Either they haven't had enough trouble with the older tools/processes that the effort of an infrastructure change is worth sinking time into, or they have other concerns with the alternatives (security, as someone has mentioned above, and code maturity concerns may be involved, though the latter much less now as it has been pretty solid for some time), or maybe they intend to move but just haven't decided on an alternative yet.

Linux was using BitKeeper, a commercial DVCS. The raison d'etre for git was because the company behind BitKeeper revoked the license for the Linux guys to use it. http://en.wikipedia.org/wiki/BitKeeper

Ah, I forgot that step.

They moved to a DVCS to solve some of the workflow issues, then Linus created git in large part because of the licensing issues.

Another detail missed in my previous post: If I remember rightly there were a couple of F/OSS DVCS's in development at the time, but he chose to write his own as some of them were not yet near stable and the others didn't quite work the way he wanted. I dimly recall some criticism for choosing a commercial product prior to git, and that decision was for much the same reasons git was created instead of using one of the other available options.
