> By offering different videos from time to time, the system is also able to get a better sense of what's popular among a wider range of audiences to help provide other TikTok users a great experience, too.

If someone else is complaining about their experience, we shouldn't be dismissive of it, it could easily be a real concern based on dark patterns the platform leverages.
For example, the platform can amplify triggering content to someone who exhibits schizophrenic traits, or it can show self harming or depressing content to someone who exhibits bipolar traits.
It's harmful to assume algorithms can't be implemented without flaws, agenda, and human bias... Actually it's willfully ignorant to think that anything inherently made by humans can be made without flaws and bias.
