I've only ever heard the term 'echo-chamber' as a pejorative against people who hold anti-establishment views, ie 'Hillary lost because middle America is stuck in right wing / alt-right echo chambers.' It's appears to be a derivation of the 'conspiracy theorists are mentally ill argument' or 'Yes, people hold these views, but its not their fault, choose one (mental illness/echo chamber).
