I agree, it’s hard for me to see the data collection of TikTok being more harmful than the data collection on any number of other platforms.
However maybe, like other algorithm-optimized social media, the real harm isn’t them collecting your data but in rewiring your brain, training you to watch a never-ending stream of more content, wasting your time, eliminating your ability to maintain concentration, etc. But of course that’s not what the lawmakers were talking about and it’s not a feature unique to TikTok.
