Actually TikTok is now the leader with teens. [0] And I don't believe the CCP would allow a sale to a US-based company, least of all Facebook/Meta. [0] https://www.cnbc.com/2021/11/18/tiktok-usage-topped-instagra...
Isn't TikTok just videos though (I don't use it so I'm guessing)? It doesn't really seem useful for sharing the same kind of information that people use Facebook for (mostly text based information, questions, etc).
They can always expand, but I feel like these social media services usually have a hard time pivoting to a different medium after their initial success.
