Competition hurts wikis significantly in attracting their audience, due to how Google penalizes overlapping content.

I can speak for Fandom staff when I say that such a middle ground is definitely known and appreciated. Users who hurt the community in demonstrable ways are more than likely valid blocks. (Fun Fact: We stopped being Wikia last year, legally.)
