I doubt that this sends back tons of data. Early TikTok was basically a standard Chinese startup in terms of how they collected data to optimize the app... It's not because they cared about what "you" are doing. The Chinese tech ecosystem is just more competitive than the US one. Most social media companies have been careless with data until they got public backlash though... TikTok's systems are probably more secure…
ByteDance is ready to close TikTok rather than divest and earn billions of dollars. Does that sound like a business or an intelligence front?
Although, they do seem willing to sell potentially.
China restricted them from selling their recommendation algorithm, and it's hard to sell TikTok without.
But, TikTok did immediately start work on an independent algorithm that has no ties to China, so that they can sell it if it really comes down to it.
