UI/UX shapes how people react to what they see. Since the reddit redesign the quality of discussion has dropped significantly. When the interface shows less than half the content it used to and it's all focused around reddit gold emojis etc instead of the actual comment chains and posts it's expected. Sure you can redirect to old reddit but most won't and you can't change the quality of content other people put out. Overall it's incredible how easy it was for me to go from several hours of browsing interesting topics daily to barely using the site.
