@dcc >you do not need to install open bsd with proprietary drivers...
Too bad, fw_update will install whatever proprietary software it possible can.

For example, fw_update will install the proprietary software known as intel microcode updates if you run openbsd in a VT-d VM, even though clearly that software is useless (the proprietary OS known as Debian does this too).

Sure you can patch openbsd to remove the malware installing script, but why on earth would you use an OS that has freedom sabotage built in?
