I've been thinking about this, too, but maybe it's a good thing. Maybe by driving people off the site, they're breaking up their monopoly. It's creating demand for more places that allow more freedom of speech and thought. My main issue w/ a lot of these online spaces is how it enables people to fully lock themselves in echo chambers that completely alter their reality and world view. That's the scarier part to me. For example, Twitter. Most of Twitter exists in a whole nother world that is entirely virtual and has no correlation to real life. You have people walking around who live in a reality that doesn't exist, and many of these people are "important" and are making decisions and driving discourse thru teaching, writing, and speaking based off this false reality they've locked themselves into.
