Dead Internet Theory meets enshitification. The internet was allowed to grow into a network primarily designed to connect companies with consumers to extract value. The people who make waves (good or bad) are banned from platforms because such waves are hard to control from the top down. That "wave maker mold" is also the original reason people went online -- there were cool people with new ideas to discuss. Now discussion is mostly argument so cool people are replaced with people just gaming whatever meta the platform is currently running.
