It’s not that they’re not active, it’s that every single thread on every single community devolves into linux discussions even if the community isn’t in any way supposed to be about Linux.
Also the ones that aren’t active aren’t active because everyone realized lemmy only caters to like three interests.
We need better moderation so that the communities which are supposed to be about Linux are, and the ones that aren’t don’t get flooded with it. That way newcomers won’t feel like they have no place here unless they’re an anti-car, vegan, FOSS user.
If this doesn’t happen, lemmy will slowly die and people will have to go to other places like Tildes or back to Reddit.
