I believe it is yes and no. Originally both were @David’s, but MaidSafe began paying for hosting very early, and when @David ducked out, I think the domain was taken over by @frabrunelle. The “official” position though is that it is not owned by MaidSafe, just supported, and that it belongs to the community at least in spirit though legally an individual owns the domain (maybe @frabrunelle).
To decentralise control I think @ioptio is the main admin though, along with @frabrunelle who actually does the work AFAIK.
Hopefully they will correct anything I’ve got wrong here!
