Switching costs are low. People use YouTube, Telegram, Slack, Instagram, Snapchat, and Reddit all day. Countless smaller forums are wildly popular for specific interests.

If they fell, whatever platform is next in line would start receiving the criticism.

But further, I think we've seen many times in tech that about the time something gets so large that people start wanting to regulate it is about when tides are shifting anyway. The thing to reduce the influence of these networks won't be regulation, it will be some combination of boredom, disillusionment, a better alternative, the next generation wanting something different from their parents, etc. To force split before that happens just ensures the market-provided solution is weaker and less revolutionary than it could be, since the competition it is overcoming has artificial handicaps. That makes progress slower overall.
