Exactly. It makes it basically impossible to get niche industry/trade information and history onto wikipedia unless it was so newsworthy it's covered everywhere.
Yet when I (or others) are trying to raise the issue on certain Reddit communities in addition to Lemmy people there still prefer to bury their heads in the sand. Often they'll simply resort to personal attacks and so on just to avoid facing the fact that Wikipedia is not as infalliable as they think at all.
I think the ongoing hosting cost of any given article is incredibly close to zero with the exception of a very tiny fraction of popular articles. The popular ones obviously deserve to be there as evidenced by their popularity alone. Maybe there is something I'm not taking into account but I have a hard time seeing the meaningful cost of some obscure wiki page merely existing.
If that's the intention, fine. But don't be surprised when no one but the most committed politicians want to bother trying to contribute to the project.
