As an American, I don't connect "fedi-" with the feds.

Yeah, what features? Polls? Community flairs? The ability to restrict downvotes to only members of a community? The ability to combine multiple communities into one overarching category? And then customize that without needing admin support, and then also share that with other users? The ability to personally block every user from an instance, again without requiring admin approval? The ability to automatically label every user that has a brand new account, less than two weeks old? Or that posts 10x more often than they comment, hence might be an unregistered bot account? Or that gives and receives 10x more downvotes than upvotes, so is at best a controversial and at worst a highly toxic personality - but again, independent of an admin or moderator, and instead being totally in control of the user? Or the ability to block posts based on keywords, but perhaps not all such posts, and instead having granularity of All vs. None vs. Some? Or offering hashtags for content discoverability beyond communities and categories of communities? Or the ability to follow anything you want - a community, a user, a post, a comment (even not made by you) - and arguably far more importantly, the ability to NOT receive notifications for something that you wrote?

PieFed has all of that, and more. Lemmy has none of it. Do as you please, but now you know. Check it out: https://piefed.social/ .

Edit: even Reddit lacks many of these features. As it enshittified, it kept adding features that attempted to boost its profitability, like various forms of irl coinage, rather than provide stuff that people actually wanted to see.
