.org was never intended to serve only nonprofit
organizations. The definitive
source on this is RFC 1591, "Domain
Name System Structure and Delegation," by
Jon Postel, March 1994. It
reads:"ORG - This domain is intended as the miscellaneous
TLD for
organizations that didn't fit anywhere else. Some non-government
organizations may fit here."
The RFC is not shy about stating the intended
function of gTLDs when
there is one. For example, .net "is intended to hold only
the
computers of network providers." And .gov "was originally intended
for any kind of government office or agency." But nothing is said
about .org
being for nonprofits only.
ICANN's claim that .org's "originally intended function
[is] as a
registry operated by and for non-profit organizations" is ludicrous.
