ByteDance is trying very hard to run TikTok and Douyin (抖音, the Chinese version) as separate companies that happen to share the same code but not data. For one, this is because they're well aware that Western governments are suspicious of foreign companies having access to their citizens' data. Secondly, having Chinese and international users on a shared platform also makes it more difficult to maintain the narrative mandated by the Chinese government, as each cross-border interaction is a potential hole in the Great Firewall.

After the lack of data separation effectively killed Grindr, they can only hope that they've done enough and won't suffer the same fate.
