it used to be the case that you would rank for your EMD keyword almost with no effort and definitely with no quality links required. Now it seems you need to build trust and authority to your website to rank for your EMD keyword.
I'd say that's exactly the point of the EMD update. .
So with this in mind, why would switching to a non EMD cure the issue for some people? If all they were relying on was the domain then changing it would spell doom for the site anyway.
For me this isn't the case as I'd say my non affected EMDs fit this description much better and still rank fine. The only affected site had years worth of credible links based around the EMD. I am still convinced we tripped an over optimisation penalty due to a combination of factors. One of those being the domain.
