For me it's just a last straw on the camel's back. The site has obviously gone severely downhill since pivoting from the old.reddit.com desktop-based site that focused on links and discussion, akin to a forum, to what it is now, an infinite scroll of half pics and gifs, half rage-bait. There is not much interesting discussion going on on Reddit these days, the change of the UX to prioritize mobile use has changed the entire nature of the site to favour short quips and less thoughtful posts. People on this board will often say things like "oh well at least if you go to your specific niche subreddits there is still good discussion being had", but even this is much reduced. Go to any long lived historically discussion-heavy board like say /r/Coffee, /r/LetsTalkMusic, /r/TheoryOfReddit, etc. If I look in the internet archive and go back 10 years, I generally find much more interesting conversations being had back then.
