You are making an assertion without explaining what you are basing it on. I am not aware of any court cases that confirm that duty of care applies when a flight is cancelled weeks or months in advance. Moreover, even if a court later rules that duty of care does apply in such cases, why would the OP need a hotel/food when they're at home? Surely, if a route is withdrawn people can't go anywhere and won't need hotels?
No one said that IG must only rebook onto its own services. This is what airlines do when they cancel routes months in advance (some do negotiate with other airlines to get passengers to their destinations). Getting a different outcome would require a legal action.
