Backfired on them, the whole OSRS community was intentionally searching for things in google and using the “official” wiki results to bury fandom, then the game devs themselves added a wiki button into the game.

I don’t care what their rationale was, it’s to claim you own intellectual property that other people wrote for you. If I write a story, and post an excerpt to someone else’s website that doesn’t immediately confer copyright or IP ownership of that to the website owner.

Even more so when the information that is your IP is copied word for word from another companies IP and iterated on by a third party to qualify for fair use.
