Personally, I can't imagine ever being interested in an extension like this. In general I think I'd prefer consuming less news (such that media bias doesn't influence my thoughts) rather than consuming more news to get all sides on "the issues".

That said, I find these sort of trends fascinating because it's producing its own form of bias in terms of what views are valid opposing views, and which views are simply bunk. I'm assuming, for example, if I read an article about a covid vaccine I wouldn't be suggested an anti-vaxx article claiming that a covid vaccine will give me autism. The decision not to do so, however reasonable, means that there is a level of curation and gatekeeping which could manifest as toxic bias in theory.
