That’s a bit doomerist of you. Why leap to the assumption that voters are against it rather than the far simpler explanation that people are unaware of its existence, or don’t feel they understand it well enough to have an opinion?
In which case what’s needed is a much stronger social media effort, preferably headed up by the organisers themselves, or someone else who can make it their entire thing, from where it can hopefully radiate out to other interested parties.
It’s really unfortunate that Lemmy handles deleted posts in this way. It’s one of very few genuine advantages of the Reddit platform. Over there, if the OP deleted the post, the text they wrote would no longer be visible, but all the comments under it still would be. And people could continue to have that discussion, so long as they had the link.
