Anyone who wants to have access while off-line, for whatever reason. This can be as simple as saving costs via more complicated as accessing content from regions with spotty and/or expensive connectivity (you're on a ship out of reach of shore-based mobile networks, you do not have access to Starlink or something similar, you're deep in the jungle, deep underground, etc) to some prepper scenario where connectivity ends at the cave entry because the 'net has ceased to exist.
I would like to have a less politically biased online encyclopedia for the latter scenario, it would be a shame to start a new society based on the same bad ideas which brought down the previous one. If ever a politically neutral LLM becomes available that'd be one of the first tasks I'd put it to: point out bias - any bias - in articles, encyclopedias and other 'sources' (yes, I know, WP is not an original source but for this purpose it is) of knowledge.
