One of China’s biggest mobile gaming companies is selling popular gay dating app Grindr for $608 million after pressure from US authorities concerned over the potential misuse of user data. National security officials in Washington fear the platform — which bills itself as the world’s largest social networking space for LGBT people — could be used by the Chinese government to blackmail Americans with government security clearances, according to media reports last year. Beijing Kunlun Tech took a majority stake in the app in 2016 and bought the remaining equity two years later for a combined $245 million, but was reportedly ordered to relinquish the platform by US officials last year.
