I've mentioned Lemmy a few times and they seem totally blind to it. They just want a like for like platform to already be established and not willing to build anything up.
Yeah, but I do find it kind of funny that people are searching for an alternative platform because of the enshitification of Reddit, but look for a centralised service that would fall for the exact same issue that Reddit has once it got popular.
That said I do think the concept of instances are confusing at first and add friction to get new users on board.
I usually point to lemm.ee, except if I know another one would be a specific better fit for the person I'm talking to, as feddit.uk might be in your case
