Just a slight correction, if you meant the "default" as in the window manager that starts on a freshly installed system: It's not cwm but fvwm. With that said, OpenBSD ships with cwm and it's trivial to switch between the two, but they are very different.
Oh, you're right, I'd forgotten that. I think it's so ingrained in me to copy my dotfiles to a new machine before I do much else that I don't usually ever see fvwm. I always add myself to doas, move some public keys around, install a few packages and then copy my dotfiles before I ever launch X for the first time.
And yes, they are very different. I remember using fvwm fondly on Slackware Linux back in the mid 90's. I had hours of fun trying to configure it to look like Windows 95 and populating menus, all in a plain text file, no gui config available! I think I read somewhere recently that fvwm is still Theo's preferred WM and that's why it's the default...

Same, well late 90s here, and yep that was my go-to on Slackware, mostly because it was quite usable out of the box. I eventually went to Blackbox, then Fluxbox, then Gnome about six months before Pat decided to stop shipping it. I went to Xfce from there and never looked back (I never liked KDE before Plasma, and 4.x is still the default in Slackware).
