So I still hang out on reddit a bit, mostly for mechanical keyboards and sports stuff, and they are very clearly letting old.reddit, and therefore RES along with it, die on the vine. You have to pop over to new reddit to do certain administrative things, and you (or at least I) can only upload a single picture on a post, and you have to use the new interface to upload a gallery. Clicking on images now often takes you to a weird new-interface landing page instead of the image itself or a page with the old interface. I think they're going to erode the functionality until people give up and then say, "whelp... nobody was using it! Time to pull the plug!"
At which point I'm probably done. Then, Dystopia is almost the last iOS app standing but I don't think they're updating it much, so I'm probably out if/when they go too.
I've sort of accepted as a middle aged man with middle aged friends and senior citizen relatives that being tracked across mainstream social media is a thing that will be in my life, so it's not even ideological, really. Reddit is just a lot less pleasant to use on the new interfaces, with the new monetization mindset, and doesn't have the "killer app" of my actual friends and family, so it needs to be a pleasant experience and community, and not feel like I'm navigating a bot-farm ad-soaked beatdown every time I use it.
