That would be an aggregator, like allsides.com

I think "non-echo chamber content" is only valuable as long as all of it is similarly high quality. In my opinion, reading diverse but low quality content (e.g. filled with misinformation, a lack of concrete information, and a lack of sensible reasoning) is not helpful.

propublica.org is pretty good.

They wrote that these things can be found in paid sources.
