This is, ah, a pretty bold claim.
I don't see it as a bold claim really at all. If it doesn't change your behavior for the better, it is useless.
If it's useless, why do people keep logging back in?
Addiction and the feeling that they are getting something out of it. When you are training, you could watch a lot of training videos, but unless you get off your ass, you aren't going to get better.
They log in precisely because they feel connected. They have friends and family on those platforms, they have people posting about stuff they care about.
Are you spending your time there? A lot of people are complaining because they don't see their family and friends unless they go there directly (like here), otherwise they get pushed content and adverts. I don't know much about TikTok, but it is a lot of random trash that doesn't help anyone. If you want to look at harmful content, look at most of the "influencers" pushing paid products.
I don't think there is a problem seeing Hive as for making money - but people could consider how that money can be made. It doesn't have to only be through content - ownership can work too - and better. It is like a business, isn't it?
People would rather be an employee.
