Eh, I wouldn't agree with that. In Germany, we had multiple top-down orthographic reforms in the past (e.g. Rechtschreibreform 1996, had many many significant, brand-new changes to make spelling and speaking more consistent) which were pretty forced, i.e. was not organic at all. I'm not saying it was bad, I like the current state of the German language - but it was not organic or democratic. Germanys equivalent to The Daily Mail even had an entire campaign against it with stickers and all.
And there is no true way to "vote with your feet" if you get punished for violating the official orthography.
Not to mention other sources of non-organic language change, like e.g. suppressing dia- or sociolects, but I also don't want to delve (hehe) too far. :P
