I'm happy that people are creating alternatives, but personally I never had a problem with Fandom.

Yes, they will monetize the content, but they'll also manage it because it makes them money. Content on fandom is probably going to still be available 10 years later. It's the same with DeviantArt, it's worse now than it has ever been, but artwork uploaded 10 years ago is still available, and it will probably still be available 10 years later. You could also say this about Youtube, Google, and many other platforms.

I hope the emerging alternatives prove to be successful, but so far I still don't see a reliable alternative for Youtube, Google, or DeviantArt (or even Twitter, Reddit, etc.). In fact, I don't think I've ever seen a replacement win in the long run. Maybe I'm just too young.
