It might require a significant amount of work to transition from the Apollo API to Lemmy. yesterday, I peeked at the Lemmy and Reddit APIs out of curiosity and they aren't exactly similarity. So, there are two potential paths forward for the developer: either build a translation layer to preserve their existing code base, or undertake a complete re-engineering of there code base.

There's also the challenge of identifying functional Lemmy instances, which brings us to a complex issue that was raised on Rust reddit thread about possible using Lemmy https://www.reddit.com/r/rust/comments/14921t7/alternative_rust_discussion_venues/. Where some concerning information regarding the lemmy dev was brought up.

This Mastodon post (https://mstdn.social/@feditips/106835057054633379) seems to imply some socio-political implications. Although I can't fully understand the context, it appears to be related to concerns about human rights oppression associated with Lemmy's developers​ (https://www.reddit.com/r/RedditAlternatives/comments/143o5xd/reconsidering_my_support_for_lemmy/

This issue is apparently severe enough that Fedi.Tips, decided to withdraw there support for Lemmy. The developers have seemingly not addressed these concerns since they were raised.

So ya, Lemmy isn't exactly a squeaky clean project currently
