As far as I understand from what they said before, they made agreements with many eastern publishers that helped them develop the game. This was before deciding to release the game on Steam. LUG is a recent deal and included this possibility in the agreement. They can’t change anything anymore because they already invested that money.
maybe, MAYBE, the brazilian server won’t be ip blocked, as it won’t be through Steam. Maybe it will be playable like kToS (unnoficial translation pack).
I would trust IMC however, if they hold the rights to manage the server, all the content inside, its your best hope.
