Its nothing special to TikTok, the only difference of TikTok is that for the USA its a first(as a foreign owned social media company). The rest of the world was under the influence of Meta and Google for decades. It was reported that Facebook did experiments like making people sad by curating the feed.
Anyway, TikTok is working great for me. I see no political or culture war content, I enjoy comedians, travellers, scientists, culture, culture commentators, songs, hot women and cats. Its like the good old days of the internet, its fantastic. Also, unlike the traditional social media, it doesn't induce FOMO. I don'y check TikTok all the day, I don't feel the urge to be on top of my feed but once I'm in I can spend hours. Much more healthier than Instagram or Twitter IMHO. Also, I see all the cringe inducing TikTok stuff when on Twitter. That stuff never appears on my TikTok feed.
I wonder if EU will find anything. maybe sharing of private data illegally?
