That's certainly one facet of the Internet. Another is the Internet being a tool for nation state actors and grifters to undermine, lead astray and pit against each other large parts of the population, plus its uncanny ability to give rise and reach to the most abstruse ideas like anti vax and flat earth and alt right and incels and Q anon and all that (which usually circles back to aforementioned actors using it as a tool to further their interests).

Historically, citizens have been much more at the whims of the rich and powerful's propaganda, and were often never exposed to differing viewpoints, let alone cultures other than their own. Now, at least, we have those things.

(I also find it notable that you'd include "alt right" in that list, as if there's no crazies on the far left.)
