EV actually causes a different "secure" UI to display in the browser. Usually it is the name of the corporate entity that the certificate is issued for. If you don't have EV you only get a padlock.
Browsers make changes like that to their UIs all the time. I highly doubt that a member of the general public would notice the difference. Heck, I doubt most developers would notice.
I agree, because I experienced it just now. I'm on Chrome 57 and just realized that Chrome certificate details UI seems to have changed sometime recently.
I remember I could earlier click on the padlock or "Secure" text, click More (or something) on the popup and it would display certificate details in developer tools (which is itself weird, but atleast it was available for end users).
Now, it doesn't give any direct way to see certificate details. "Learn More" just opens a support page with vague details. The only way for a user to see details now is to explicitly launch developer tools. I find this logic a bit weird. Apparently, this is not a bug but a feature [1].
You just made me look, and what I saw made me sad. Even more than I already was. :(
"Let's remove this thing that is super useful while your stated goal could just as easily be reached while keeping the original functionality." Bill Hicks was so incredibly right about marketing.
The business is not the user for SSL. It's the human logging into the website. Maybe Bank of America will care if the padlock in the URL bar is gone, but John Doe couldn't care less and probably has never noticed the green padlock and word secure in the URL bar ever.
Yes, you are correct, in that Symantec's customers will care.
I am saying the customers of banks don't give a damn about EV or not. It's not in the literature. It's hard enough to train them not to click through; even I as an IT guy would probably not notice the lack of EV unless there were a modal or bubble saying "Hey! This is different!"
