"The law seems to be building up the Great Firewall locally in Hong Kong. Personal freedom on the internet will be eliminated," said Charles Low, the chairman of the Hong Kong chapter of the Internet Society. "If you say something wrong they can request the service provider to give your IP address or mobile number so they can grab you." Experts point out that China's Great Firewall -- which allows the government to inspect data as well as block IP addresses and domain names -- could not be immediately replicated in Hong Kong, home to several private internet service providers and internet exchanges. "It will take at least a few years to build up the wall," said Low, adding that what is more likely is a partial blackout, cutting off access to certain sites such as LIHKG or Telegram. "People are indeed kind of panicked and trying to install VPNs and have no idea what it can and cannot help," said Low, noting that volunteers have been holding workshops to teach residents how to use such tools and how to better protect themselves. "I have faith in Hong Kong people. They will not forget about the freedom we once had." "[T]he measures could go even further than in mainland China," adds The Guardian. "The law covers not only permanent residents and foreigners within Hong Kong, but anyone seen as violating the law, regardless of where they are in the world. The security law may also add to the Balkanisation of the internet, with countries having their own fenced-off versions, and major international tech companies will be under pressure not to contribute to that."
