Really we don't want to force users off, we want users to want to leave because of how reddit treats it's free labour and content or for reddit to actually work with the subs it's demonizing
This unfortunately is the truth, at the end of the day they will just find new moderators who wont be acting for the users or at least the majority. I'm a mod and although I want this to work and it may still have some impact realistically mods are powerless. Only users talking with their feet can really make a long term difference and there isn't a like for like replacement yet..
A lot are on discord, but the mods are looking at an official Lemmy alternative. At the moment lemmy.ml is having significant issues so I'm not sure how that's impacting federation, but hopefully they improve their servers soon..
Personally I don't think Lemmy is really a great alternative in its current state especially with servers being able to defederate other servers, meaning that users registered on Beehaw for example can't now view communities hosted on lemmy.world which seems to entirely defeat the purpose to me..
Also as many people come to r/homelab via Google, putting cache: before the https:// in chrome will yield the google cached page, which doesn't go to reddits servers. Also to be clear the mods of r/homelab have no intention of nuking the sub and losing any existing data but appreciate the efforts being made by users and r/datahoarder.
