Wouldn't it be better if fewer people used TikTok, given negative impact of social media on individuals and society?

Wouldn't it be better if these investors lose money on this investment?

Depends. Better as a word is a little too wide to interpret accurately without some additional information to go on. For example, if you look at my post history, you will know that I am not too keen on social media in general. From that perspective, it could be interpreted as a win. And yet, I think most of us here recognize the development as a whole is not 'good' ( since we are going with generic, not-easily-defined verbiage ).

Yes but how likely do you think it is that that will happen?
