Why do you feel it was dyn? I got that email and didn't remember it referring to anything in particular. I just took another look and here is the copy:
"In today's demand-driven marketing world, getting email into the inbox and sending that email is as crucial as turning on the lights in the morning. Social media is awesome, but when it comes to the most trusted form of communication with customers, prospects and fans, email wins hands down.
See that graphic above? That's a screenshot from about an hour ago, a visual representation of where emails sent through our servers are being read at that instant around the world. At a billion+ messages sent a month, there's no better time to move your email delivery services to Dyn.
We've relaunched our packages, introducing an entry-level option for just $3 per month -- roughly the amount of a large coffee. Isn't your transactional email program worth more than that?
It's time to deliver through Dyn. Sign up now. Send today. Be successful tomorrow."
Explain why you feel that a) dyn sent this in reaction to the "situation" and b) even if they did how this was a bad thing.
By the way here is the dyn.com blog post I'm not seeing anything there that dovetails and makes them the company the OP is referring to:
