Do you see anyone claiming the opposite? The point is that they will not write the motto on your license plate if you object.
I get that HN attracts a certain amount of pedantry, but I can't figure out what exactly you're even trying to be pedantic about. There's not single comment here that could be reasonably interpreted as suggesting that "live free or die" isn't their motto
His pedantic point is that due to the way the original question was written, the answer is “yes” regardless if you object or not.
The question was “isn’t that the state with license plates that say ‘live free or die’?” And even if you get a license plate that doesn’t say it, NH is still the state with those plates
