Check out !worldnews@lemmit.online. The admin of lemmit.online has set up a bot that fetches reddit posts via RSS, making it much easier to make the switch and of course not getting any ads.
Also, these posts can then be cross-posted to help us create more content on lemmy native communities. Although I do recommend removing most of the post body when cross-posting. Alternatively you can turn the cross-post into a native post as if you simply were sharing content that you’ve seen on reddit, but with the perk of not having to load reddit.
You can make requests for subs to fetch at !requests@lemmit.online.
In the end we’re just using lemmy and lemmit’s bot as a simple RSS reader, so nothing illegal or even remotely unethical happening here.
Community is much smaller on this side of the fence, though.
Honestly reddit is about 100 times too big now. Most comments on major threads go unseen. It was plenty big enough 16 years ago for lots of good discussion, way better than today to be honest. Now it’s just about who can get the quickest quip in. Actual discussion is pretty lacking on reddit.
