While this is true, I feel like there really is a difference between modern online communities and the ones that existed in the older era, before the so-called web 2.0 era. You can't escape bias at all, that should be any person's educated perspective, but there is a difference in degree that is sharper both on reddit and facebook groups and the like.

Ironically, twitter (which does skew left wing at least in some places), while having its host of issues, has a much lower degree of echo chamber-ness because there are no groups, everyone is thrown in a pot together. It does have the cancel mobs and all that but an echo chamber it is not, which at least proves "echo chamber" isn't the default final state of any social media platform.
