Earlier quoted context omitted.
That makes much more sense though, you're changing from something less known to more know, easier for tourists etc. Changing to a less approachable vertical system is different...
While I agree with you, that is a very occidental point of view. I think it is important that the system they are changing to is better for Mongolian people, not tourists. If people there is more familiarized with this vertical system than left-to-right with a latin alphabet, I do not think it is fair to call it "less approachable".
This very charitably assumes that this is the will of Mongolian people and not just the will of the government.
Nowhere in the article does it mention that there was a referendum on this, and I am certain that almost anyone on HN would agree that one is necessary for a change as serious as this, upheaval of the language itself would have very serious consequences that could potentially last centuries.
