This is just not gossip. It's not about Sergey Brin's love affair.

Actually it feels to me like they're stealing it anyway they can... so if there is a legal recourse, I think it's safe to assume they've taken it, along with many illegal ones.
The territorial water is 12 miles wide, it's far. Exclusive economic zone is 200 miles wide, it's really far. Who want to be that far from the coast in the winter without a good reason on the most powerful and dangerous ocean? In the article they say 3 to 7 miles, that's completely territorial and for a good reason: on the first winter storm they'll be plenty happy with sovereign state helping them shelter the thing and save everybody.
Moreover, how do you anchor the thing in international waters? It's very complicated and expensive if the water is deep (which is more or less implied by 200 miles from the shore).
