The Stockholm metro is run by MTR, but they don't own it.

They're only staffing the trains and platforms, not to different from e.g. a police station paying a sub-contractor to sweep their floors and manage the reception desk. The police station is still mostly a government run thing.

For example, MTR doesn't invest any money in new lines/tunnels, or buy/maintain the trains.

I don't think it's fair to compare it to this Korean line, it's not apples to apples.
