TikTok doesn't promote this "legend" whatsoever. Indeed, 99% of the time I've read about TikTok's algorithm, it has been naysayer conspiring about how it's an evil addiction engine.

I've seen zero articles technically praising TikTok.

Like everything, it probably isn't for everyone (as an aside -- it seems like a considerable portion of TikTok's base now are middle aged...they aren't targeting any particular demographic), but personally I get a wonderful selection of FYP videos. I only use the app every week or so, but when I do it is one of the most interesting, entertaining digressions available.
