To those that are wondering: Yes, when the first Dish Online product was released in late 2009 called DRA or Dish Remote Access, the stand alone slingbox support was added in 2010 with remote viewing support and then the sling adapter was released later in 2010. Then there was about two years or so where Dish slowly rebranded DRA to Dish Online and somewhere along the line, Dish management made the decision to removal all support for stand-alone slingboxes for the 'dish branded' remote access apps and websites. Dish pulled stand-alone slingbox support from the Android in 2011 and then in Q3 of 2012 for Apple iOS. Then at the end of 2012, everything has been rebranded again as Dish Anywhere.
For what it's worth, I also received the call offering me the free Sling Adapter and I accepted. I've been using it for a few days and while they've certainly improved the integration miles ahead of where they used to be, it's still really buggy in the iOS app (I haven't tested with Android yet as my iPhone is my primary device), particularly when I'm viewing the recorded shows list, in many cases, my recorded shows have no information about the show (it's just blank) but it does show data on the full Dish Anywhere website.
