After a quick search, I couldn't find a source that claims that any website is blocked in Hong Kong, and several that claim that no website is blocked.
The Internet connection is monitored, there's pressure and self-censorship, but there's no blocked access to websites. It's easy to be bigger than zero.
EDIT: The biggest collection of the websites I could find lists 1129 that are still blocking access to EU citizens, and 252 that stopped (presumably, once they've become GDPR compliant): https://data.verifiedjoseph.com/dataset/websites-not-availab...
While I agree that there is pressure from pro-Chinese Government henchmen to intimidate free press in HK, I am curious as to where you get this assertion that the internet is monitored. That would imply some kind of government surveillance. I have never heard of any systematic internet monitoring in HK of the kind done in other countries, like mainland China.
this is not a right/wrong issue. like most of reality, it's full of grey.
Care to share some examples?
GDPR on the other hand has absolutely no political selectivity. It's just a bunch of self selected US sites that can't be bothered to properly implement GDPR (until they get their own version of it).
That makes your claim about the number of websites accessible from Hong Kong about as relevant for freedom of speech as the lack of chlorinated chickens in Europe's supermakets for the variety of food we get to eat.
