OpenBSD "As seen here, PF is now enabled by default. The default pf.conf will now pass in all traffic, except for TCP port 6000 normally used by remote-X11. By having the X server still listen on port 6000 but let PF block incoming packets that aren't coming from localhost you can still use local X sessions that needs to talk to the TCP port or runs through a port forward from remote, but at the same time don't expose your machine on the network. Recent changes to PF, like having packet reassembly enabled on all packets by default, will now help clean incoming traffic."

I think you're confusing having most services turned off with having pf on... turning on pf with the default install is new, they still leave most daemons off to have a 'secure by default' install.

This doesn't mean they used to have pf enabled but blocking everything... that wasn't the case in the past

They always have had the minimal services needed (meaning daemons aren't listening on ports), which they still do, but with the added benefit of pf being on but allowing all traffic except for the mentioned X tcp port
