I honestly doubt that. He's not stupid. He knows the community can fork indefinitely and he can't buy up tokens indefinitely. In that game of attrition he could never win and it would not be hard for him to see that. 

Now, it is possible that he is accumulating so that he can get enough Hive tokens to devastate Hive's economy by performing massive dumping. That would be effective economy warfare, but if he is accumulating its not to take control of Hive because that game can't be won.
