Earlier quoted context omitted.
I'm not parent, but the very fact that they keep degrading the UI and implementing dark patterns and doing crap like requiring login to read comments is exactly what gives the impression that reddit is dying. It is hard to assume that people on top care about their users when every single news about any kind of change looks like to a downgrade to my Reddit experience.
I'm still baffled about the UI "improvement." It's comically bad. It's so busy and I can't find anything I want. I have never, ever seen a site anywhere near as big as Reddit with such a bad redesign. It seems they could have hired one UX guy and one graphic guy... I could probably pay some people on Fiverr $100 total to create a better design for the entirety of Reddit. The old design was boring and out of date, but…
One of the things the new design has made much harder is the discovery of new subs; in the old reddit you could generally speaking find a list of related subreddits on the right side of the screen. Not anymore (sometimes they're buried in the wiki, but not always). It's a shame, because discovering new and interesting (and weird) topics was one of the best things about it. Also, to echo many users here, my usage of the site has dropped right down after the redesign. It's a shame because it was for many years one of my favourite places on the Internet.
