Well, say a weather data service is provided by the government but is only allowed to operate as long as they don't compete with a commercial service. At that time there is no commercial service so it's fine. 10 years later a commercial service is started and now the public service has to change because that's what the law says. The public service didn't do anything wrong and didn't change anything, but because something in the private space changed the public space now has to stop providing a service. That's what I meant by change in the weather data example.
