thats the entire point of mastodon.
literally why it was built. Edit :
It’s not supposed to be a place you go to get served content. You pick who you follow, and that’s your feed.
The problem has been lack of adoption by popular news and culture . So you go there, and you cannot easily find high volume content provided like the bbc, nfl, Real Madrid, Activision, etc etc
Genius and great value.
