I still think nationalizing is a bad idea. There is no legitimate competition between railroads whereas mobile ecosystems can compete.
Mobile app stores are more like banks - a big problem when there are not a lot but a problem that can be remedied by having the government compete (e.g. with a post office bank).
The government could set up a competing app store, that might not be a bad idea, actually. They could hardly do a worse job than google and apple at vetting app developers and it would put a firecracker up google and apples ass.
