Correct.

I'm a little surprised people don't know the ownership story on HN. Didn't it raise questions when they realized they can't delete their posts without mother-may-I'ing the mods?

HN is pretty up-front that when you post here you are providing them content for free to more-or-less consume as they please.

I disagree on the up-front... front. Neither of the things you mentioned are made clear when signing up for an account.

The onus is on you.
