Do you have any experience with a Eu country internet regulatory service?
I have experience with the CNIL (The french one), and they were helpfull and yes, good-natured. Part of our demand to be able to host data from hospital was drafted with their help, when they had no legal obligation to help us.
A friend who work in a legal/tech startup also had good experience with them, and i don't know anybody who ever had a bad run with them.
So if you have contradictory experience, please share them. Until then, i'll still take all this "GDPR will kill tech companies" articles from people who only experienced the US legal system as jokes.
