That's interesting. Some of the fandom wikis are really high quality (memory-alpha, starwars) and were my introduction to the service. I suppose I appreciate that someone paying for the hosting and running the wiki has to be paid for somehow. And this kind of consolidation makes it worse if the underlying provider fails, but ideally avoids that so individually hosted instances don't more silently disappear. It makes me wonder about the most reasonable balance.
I also enjoyed browsing the list of mappings:
