22 # o OpenBSD team wants to get changes incorporated into IPF. Darren no
24 # o Ask again -> No respond. Darren coder supreme.
25 # o OpenBSD decide to make changes, but only in OpenBSD source
26 # tree. Darren hears, gets angry! Decides: "LICENSE NO ALLOW!"
28 # o OpenBSD team decide to switch to different packet filter under BSD
29 # license. Because Project Goal: Every user should be able to make
30 # changes to source tree. IPF license bad!!
31 # o Darren try get back: says, NetBSD, FreeBSD allowed! MUAHAHAHAH!!!
32 # o Theo say: no care, pf much better than ipf!
33 # o Darren changes mind: changes license. But OpenBSD will not change
34 # back to ipf. Darren even much more bitter.
35 # o Darren so bitterbitter. Decides: I'LL GET BACK BY FORKING OPENBSD AND
36 # RELEASING MY OWN VERSION. HEHEHEHEHE.
