These would be interesting challenges in a world where capitalism still exists in half of countries, and socialism exists in a variety of progressed stages, but,

I imagine the company is nationalised by the country it’s headquartered/mostly managed in. Nationals/Allied socialist states get free/subsidised service (ie commissions and purchases), everyone else pays as usual. Efficiency savings for the socialist nations is a net benefit anyway, with the bonus that capitalist states subsidise it, job done.
