The companies targeted by the nationalisation of assets order were ATC and Tenloss. It wasn't a general order to nationalise all private enterprise in Republic space, though there's obviously a bit of a snowball effect.
Some Mandalorian leaders are pushing for war though. There's a clan leaders meeting about it going on right now.
Don't have the link handy, but in another thread Republic troops execute former functionaries of the Imperial Remnant (which is quite ironic).
Speaking for myself, Sio views the whole affair as an internal matter of the Republic and doesn't want to get involved unless it spills over. Firemane's frozen its old contracts with the Republic and helped Salacia evacuate its property from a Republic due to the business ties with [member="Judah Dashiell"], but is staying out unless the Republic messes with it. Of course, though on the Sanctum council I can't speak for all of SSC or define what its 'official' position is.
