What people want isn't necessarily what they need . When people's needs are satisfied, they want more of that . So let's satisfy their needs instead. Echo chambers are ultimately self-defeating as they bring on more divisiveness and intolerance.

If we accept that humans are social creatures, and social media is able to connect people, then it is possible to say Internet comment sections are able to fulfill some needs that people have. Displaced football fans working far from home may not be able to find a local group that also supports their home team in a far away place, but there's a digital clubhouse for the displaced fan's home team somewhere on the Internet.
This may not satisfy a need like food or water, but people organized into geographically-based, sometimes tightly-knit communities before the Internet. That modern technology allows us to organize into loose-knit communities through the use of "Internet comment sections" is to realize J.C.R. Licklider's dream of an inter-networked computer system.
