Reddit moving against my preferred clients. I'm not abandoning the site completely until both third-party and old.reddit is gone, but thought I might as well have a foot out the door. Lemmy just seemed like the most closely related option.
This is basically the same reason for me. I'm purely using old.reddit.com on desktop and rif on mobile (though I rarely browse on mobile). Once old Reddit is gone for good, I'll be leaving Reddit entirely.
