I never said anything about it being wrong or that anybody was getting hurt.

I just said under current definitions it is illegal. Legality != morality.

I totally agree.

That’s not related to the original post though.

Especially when the statement makes no sense

No, that would harm whoever was in possession of the room at the time (owner or guest).

This would be more akin to sneaking into a movie theatre to stand in the back and watch.

But that would still be theft of service.

While I appreciate the sentiment, theft of service is a crime. You don’t have to be able to own something to be able to steal it.
