You're right, getting sued for pointing this out would be absurd. But where you're wrong, is that just might've happened. There are more ridiculous lawsuits out there. There was a story on here a couple of years ago where a US Government real estate web site was using JavaScript for their authentication, with the password stored in plain text. When it was pointed out to them via email, they responded with allegations of computer fraud and threatened to file charges. Obviously they weren't 100% serious and I'm sure nothing official came of it - but yes, people this stupid are that ridiculous.
