To me it seems that the worst accusation you can level at a news org like NYT is reaching for sensationalism and lurid "entertainment" to get clicks.
But they are a (subjectively) trusted/credible news institution. There is an underlying mission and set of shared journalistic values behind what they do, not to mention an editorial process. Through these things there is at least a nod towards accountability.
TikTok creators are not credible or trusted in the same sense, and they are under no obligation to a larger mission or set of norms, self-imposed or otherwise. They just want followers. With content like this, it seems they're doing the inverse of the NYT - they're reaching for credibility by creating content with the appearance of journalism.

And to your point about consent, I'm sure there are people who did not or could not consent to their image being published. AFAIK there are no structures governing TikTok "journalism" that would prevent this sort of harm. For me, this is enough to totally disqualify this sort of thing as journalism.
