I hope this is not because of the conquest against misinformation, Google heavily preferring "authoritative voices". If a term fits anything out of the news circle you get endless amount of articles of the same. They use different words but it is always the same content.
Although many people in their usage patterns are to blame too. If everyone forms a non-crawlable discord community, you should not complain about a lack of discoverability. IRC had the same problems but at least there were always alternatives with forums.
A button to filter any kind of media publication would really help.
