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.
Tbh I don’t really care about the fediverse, I just wanted to find the communities that I lost and if I can have them in one place again, the better. It’s not that I can’t understand why would you want the fediverse for the fediverse, but I only learned about it to do what I came to do and didn’t interest me beyond that.
