'Blamed and shamed'?! I don't even think it's an issue, your wifi password isn't that of your bank account. They store your emails unencrypted for crying out loud, wifi passwords pale in comparison. It's a non issue.
My gmail is my personal email choice. I know the risks associated with that and accept them in return for the convenience of google email. On the other hand, my employer may not like that google has the password to our company's internal wifi. That's why I think there may be a bit of an issue here.
Note that I can probably get your bank account password with your wifi password, when you'll be annoyed and hit that "ignore warning for invalid SSL certificate" ;-)
