I'd argue that Wikipedia and its 'sister' projects have accidentally cannibalized a sizeable fraction of the former 'non-commercial, non-business focused' Internet of the 1990s and early 2000s. If you're providing information in a way that's not intended to further some sort of profit motive, it makes sense to work within that large established project because that maximizes the resulting exposure. The rise of LLMs only makes this starker, every LLM is trained from Wikipedia.

Interesting take. Do you mean Wikipedia has cannibalized the traffic to these web sites or do you mean that Wikipedia lead to these web sites going offline altogether?
