It’s not often Silicon Valley gets behind a single cause. Supporting net neutrality was one, reforming government surveillance another. Last week, Big Tech took up its latest: halting any cooperation with Hong Kong police.

Facebook, Google, Microsoft, Twitter, and even China-headquartered TikTok said last week they would no longer respond to demands for user data from Hong Kong law enforcement — read: Chinese authorities — citing the new unilaterally imposed Beijing national security law. Critics say the law, ratified on June 30, effectively kills China’s “one country, two systems” policy allowing Hong Kong to maintain its freedoms and some autonomy after the British handed over control of the city-state back to Beijing in 1997.
