There is no universalizable qualitative difference between filters that create a bubble/echo chamber and filters that do not. The word echo chamber and bubble are just meant to transport a value judgement against their existence. Which is why people often talk about other people's echo chamber and their own legitimate anti-abuse filters.

If you hold a non mainstream position you would probably want to teach your feeds to stop bombarding you with the respective mainstream position. A hundred years ago you did that through selecting a fitting club or reading a specific newspaper over another. Today you adjust filters.

What's creating a "dangerous level of false consciousness" is IMO just ignorance and media illiteracy. If people think their media diet is also everyone's media diet, they just weren't properly prepared for sophisticated media.
