My guess is that large companies may be required to switch to the geolocated national language preferences of a countries government so that a nation preserves its identity. If you are in the USA and you can switch your language preference to the UK your mindset starts to trend towards UK thinking. Region locks on DVD's and Blu-Ray disks may have a similar purpose, to preserve local culture. This seems both good and bad, bad in that it discourages cross-cultural exposure and thinking, and good in that it makes the world richer because cultural diversity encourages many different approaches to life which may benefit everyone whenever cultures do mix, sort of a redundancy of operating systems so to speak.
