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