Last month, the alternative project Justapedia was launched which is accessible through the URL https://justapedia.org. It is a complete English Wikipedia fork made sometime last year.
Unfortunately the front page showcase doesn't give it good optics because it gave the impression of trying to "whitewash" fascism. They'll have a better public opinion if they tried to fix the Holocaust distortions as revealed by Jan Grabowski and Shira Klein, and put that into the showcase.
Besides, there are alarming rumors I saw in Y Combinator that Wikipedia/Wikimedia have unreported harassment and pedophilia scandals.
