Fan subs are an enabler for promoting culture and stimulating tourism. So it goes without saying that the administration of Holland doesn't at all mind that someone outside of Holland is making subtitles for a Dutch TV show or movie in English, or Hungarian, or Spanish or what have you.

I suspect they are just caving in to pressure from outsiders. If I were to guess, English-speaking outsiders from America.

Hey, look who is a member of this "Dutch" BREIN group: the MPAA.

If Holland weren't in the EU, they might have the guts to tell them to go home. "We don't mind Dutch TV and movies being subbed in English by American fans, so we expect the same in reverse; have a nice day".
