I don't feel weird about it because it's a trillion dollar business, and it's in their best interests to muddy the waters regarding any cohesive argument. But when you just look at these things from first principles, boasting about 1 billion hours of shorts watched in a month or something ridiculous like that, AI generated content on loop, teens/adults getting into status/envy games on these platforms, the "connection" aspect looks like a very small positive.

I don't think your example of off-label Ozempic is isomorphic - the more apt comparison is one I already gave: Why did it take us 30 years to realize cigarettes cause 400k deaths a year? The answer is because there was simply huge amounts of money involved.
