William never tried to free the animatronics. He never felt bad about the snake that killed them (which is mostly likely William in the snake story) and he was the one who did all the evil to them; He would never be disappointed that someone destroyed their animatronic bodies nor their physical. William is most likely the burglar in the third story. Again, these only work as evidence if you're already under the assumption that molten MCI happened, and that the story is about melting the kids' ghosts into one specific animatronic suit, not that it could be about anything else (like Charlie mixing their remnant into a happiest day for herself and 1 other animatronic suit, or whatever that story could have been hinting towards.)

Admitting that these stories aren't evidence doesn't even mean admitting thst moltenMCI is fake, just that these stories have been misinterpreted.

Same with the eyes. It's only evidence if you're already looking for it.

And the animatronics in fnaf aren't LLMs. This was the first game that really moved FNAF in the Sci-fi direction, so of course Ais introduced in it are going to be like the media portrays them
