SSL encryption
People seem to mis-understand what level of security SSL encryption offers. You can make a web form that collects user data and have this sitting behind SSL. Let's say one of the fields on the form is your password. The SSL cert will help protect that as it's posted from the form to the server. However what happens to it once it reaches the server (e.g. in terms of storing it to a database) is a completely different matter. Just because the site uses SSL does not mean anything in relation to the encryption used when storing/processing that data beyond the initial post.
Their privacy policy said "all information that you provide will be protected with industry-standard protocols and technology". To not use a salt is arguably poor practice, but I even reckon it's not considered industry standard to do this by some devs anyway, so it's not clear cut.
As for "admitted that they had not read LinkedIn's privacy policy prior to the hack"...well that just tells you they were trying to make money from this retrospectively.
