That still exists in some ways. But much of the Internet is very much being gatekept. Including YouTube, Wikipedia, GitHub, Reddit, and Hacker News. There is almost no point in posting things publicly anymore because not only is the average user not genuinely interested, but they are genuinely not interested. That is why kids grow up with TikTok. Because it is one of the few platforms where you can post on almost the same terms as you consume. And thereby experience those network effects.
