This is why I run a set of rackmount servers at home, that have the media and apps that I want to consume. If my ISP bites the dust tomorrow, I've literally got years worth of music, books, tv, movies, etc. Hell, I even have a bunch of models on ollama, and an offline copy of wikipedia running (minus media, obv) via kiwix.
It's not off-grid, but that's the eventual dream/ goal.
