Yes and No. Essentially Kara/Walt and WSJ/Dow Jones/NewsCorp "divorced".
The "divorce" left Kara/Walt with the writers (as they were employed by them) and WSJ/Dow Jones/NewsCorp the AllThingsD brand, website and conference business. However, it appears the AllThingsD site is being completely shut down and redirected to http://wsj.com/tech - probably because NewsCorp who struck the original deal with Kara/Walt don't want a situation like this to happen again.
Recode is a completely new business (site and conference business; WSJ/NewsCorp/Dow Jones still owns the D Conference) albeit with the same writers from AllThingsD.
