TLDR: The main reason was Lemmy hogging server resources.
Last year, during the Reddit 2023 API controversy I finally deleted my account and moved on to Lemmy. Here’s a look at my experiences and why I eventually decided to switch to PieFed.
Ha, yea! If you know rust, then you don’t need to reach for Python (right?!). Plus the main motivation was to contribute to lemmy itself while also learning rust. That another platform is good for personal instances doesn’t change that, though piefed does seem cool and I can see myself wanting to get involved with it at some point.
