Jason, you say "..companies with TMs would have a .reg, it would make it harder for
companies to argue that someone using a domain for which they have a TM, was passing
off as them."That is one of the main points - NOBODY COULD PASS OFF AS THEM.
e.g.
In the case were Nissan cars tried to 'STEAL' nissan.com from Mr Nissan (using it
for his computer business):
If he decided to sell cars - he could not PASS OFF
as them, because nissan.com would not be redirected to nissan.car.us.reg
If you
believe in the First Amendment (apparently the US Government do not), then nobody
has the right to tell you what words you cannot use.
As the saying goes, "I might
not agree with what you say, but I would defend your right to say it".
