I did not get from TFA that the Dutch don't like English. Also I don't think that's true at all (source: I'm Dutch). According to an older HN submission (can't find it right now) the netherlands is, with the exception of the UK, the country with the highest percentage of people speaking English (96%), and I don't know of anyone not liking it.
Good to know it is just this organization having the awful ideas. ;)
Btw- I've worked with some great Dutch developers and am in awe of all of the talent there from the things I've seen over the years. The language isn't bad either. :) Just saying it's a mutt language like English, but mutts are good things. Diversity is a strength, not a weakness.
