A speaker icon isn't making a judgement as to whether that sound is good or bad. Turning no-ssl into a warning is like having the browser judge you for being poor or cheap or incompetent. Not having HTTPS does not mean that you are insecure, it means the site isn't encrypted. There's a difference. Whether the lack of SSL makes you vulnerable to shenanigans depends on a lot of factors having nothing to do with SSL encryption and everything to do with the site content and what one may gain from snooping on your request or manipulating the response. Sometimes there's nothing to gain there.
