The epistemological collapse we are experiencing wasn't caused by information being online and disseminated via browsers.
It was, and is, caused by a mass of uninformed people, with strong tribal behavior, shutting out any information that doesn't fit their preconceived world views, and industries and politics designed to benefit from that behavior.
And btw. misinformation can be, and has been, spread via print [even today][1].

The new methods of spreading information are the problem, and it's unclear just exactly how we're all going to adjust.
