So structurally I don't have an answer other than I know that what reddit became is a cancer. Structurally lemmy should find ways to counter commercialization
. One way is to avoid boxes. Communities should be more random and chaotic.
I also would push that mods should take a back seat and give back control to communities to upvote and downvotes content they do not want to see.
Recreate what was fun about the internet before the facebook's and Instagram came. It should be pro community but hostile to capitalization.
You all deserve this and worse. No reason to complain about it. This is what everybody wanted.
