You know what I read that as Howard Johnsons. My bad.I'm not familiar with the Andrew Johnson Inn, but a quick internet search (not Google!) does not indicate a chain. The person making decisions about default behavior of software may be far removed, but the decision to choose different software based on its default behavior may happen closer to home.
I wouldn't read too far into it because most web filtering applications block access to firearms sites by default.
If the wifi was free I'd say they can have any rules they want, of course I don't have to like them or use it.
Now - if I paid for the wifi, I'd be upset about blocking rules.
