Based on how …certain… Lemmy instances have handled themselves, the intention to deal with “Wikipedia content moderation” here is almost certainly not to make a freer version of Wikipedia, but to make heavily censored content enclaves with the same obvious editorial restrictions concerning certain topics you find on certain large instances.
I mean we have seen how the Lemmy devs approach certain topics, and it is definitely not with a preference for openness or free exchange of ideas. There are certain topics here which have a hair trigger for content removal and bans, for extremely petty and minor “transgressions,” so the motivation here seems pretty transparent.
