Sorry Matt, but you bid without asking. Regardless of your attitude towards Maestro, that's a hostile bid, and he has every right to bid back or debt-bomb you. Next time, send a quick message first. It won't destroy your country to wait 6 game-months for a reply.
Picking out once good corps that has yet to get a good value for hostile bidding.. thats a act of war indeed. If a player wants go RP commie style or whatever within their nation, sure go ahead and nationalize. But to try to expand ones own ceo at the expense of another active CEO is a big no no (if ones want have friends and not get gangbanged at warlevel 3).
