On Tuesday, an extensive internet limitation tool dubbed the Great Firewall of China came into force in Hong Kong. China’s Great Firewall allows the government to analyse data and block IP addresses and domain names.
As part of the controversial new national security law, the Hong Kong government gave its police force new powers to censor online content, force internet providers to disclose user data and shut down websites.
In wake of the news many in Hong Kong deleted their digital records for any traces of approval or support for the pro-democracy protests.
Charles Mok, a pro-democracy lawmaker who represents the technology industry, tweeted: “We are already behind the de facto firewall.”
The new power means Hong Kong is losing one of the freedoms that differentiated it from mainland China: a free and open internet.
Chinese law bans access to sites such as Facebook, Twitter, Google and most major foreign news websites.
The new legislation provides authorities with the right to demand Hong Kong residents and companies to remove content, or access to content deemed jeopardising to national security.
Those who fail to abide by the requests can be fined or even imprisoned.
During investigations, police can surveil communications and confiscate electronic devices.

Political groups have already dissolved and activists have deserted social media channels, while others have erased old publications.
Glacier Kwong, a digital rights activist, said: “We had freedom before and now it is being taken away. It is extremely painful for me to experience that.”
“There will be a loss of information available to the public because people are afraid to speak up.
“They are controlling the discourse, how people can think about things and what they can think about. It’s very dangerous.”
