>who controls the rest of the money? Could be the same people, just indirectly, via friends or shell companies incorporated in Switzerland
you're absolutely right :
" The idea, according to documents on the Tezos website, was that the foundation would raise money via the ICO, then acquire DLS, the Breitman-controlled company that has been developing Tezos. "
So it seems that the plan was that Breitmans would take as much money as they want (can we say "all the money"? :), and probably the foundation guy that Breitmans are fighting now did bait-and-switch reneging on the agreement to buy the company (as it would be hard to believe that even in Switzerland such agreement can exist in a legally binding form) and chose instead to have all this money to himself. $400M of free money can do that to people :)
