Of particular concern, according to the letter, was general wording that could give police the power to impose fines and arrest local employees if the tech companies are not responsive to the new doxxing rules.
"The only way to avoid these sanctions for technology companies would be to refrain from investing and offering their services in Hong Kong, thereby depriving Hong Kong businesses and consumers, whilst also creating new barriers to trade," the coalition wrote.
In a statement, the Asia Internet Coalition said the letter reflected an industry view, and not the policies or plans of any specific company. The Wall Street Journal first reported the existence of the letter.
Since the Hong Kong pro-democracy protests of 2019, debate over online speech has often focused on doxxing. After police stopped wearing identifying markers during the protests, a slew of sites and channels cropped up to identify police. Pro-police sites, in turn, released information on protesters.
Authorities have already used the national security law to curb the practice. In January, the first known website to be taken down under the law had posted personal information about police. Under the new rules anyone posting personal information intended to harass, threaten or intimidate could face up to five years in jail and a fine in excess of $100,000.
Doxxing is just one part of an ongoing proxy fight over internet freedoms in the city. Shortly after the law was enacted, Facebook, Google and Twitter all said they had suspended responding to data requests from Hong Kong authorities. Last month, police in the city invoked the law to briefly pull down a website that called for unity among expatriate Hong Kongers in the pro-democracy movement.
