Correction, its been getting worse for 10 years and is now at a point where if you mute every sub that is at least 50% politics in the top posts of the last month you are left with nothing but "50 year old women on facebook share this" content on your feed.

Further, moderation has completely gone out the window. Personal attacks on right wing figures are almost completely ignored even in "serious" discussion subreddits. Good faith attempts to criticize the "sky is falling, nazi's in white house, everything is on fire" narrative are downvoted to the point of invisibility and no good faith debate with those points occurs. When you post verifiable proof that someone is wrong, people just stop engaging if it goes against the hivemind.

Huge swaths have become places for corporations to astroturf and shill for their products and services.

Even the pornographic content realm has been almost entirely co-opted by so called "content creators" who use the site to promote their subscription.

The average Redditor no longer cares about the truth, they don't want to have their ideas challenged, they refuse to engage in honest debate and the primary utility of the entire website has become a place to circlejerk about how terrible anyone right of center is.

The niche interest and hobby communities that aren't complete trash are low activity enough to keep a front page from being useful or a lot smaller than a better forum for the same information somewhere else.
