I have installed Linux on all four of my laptops, and I'm hoping to migrate from my iPhone to a Pixel with DivestOS as soon as I move out of my parents' house (I'm currently 17), or sooner if possible.
I have also swapped many web apps for desktop apps, and my music collection has been based around CDs and DRM-free files since it started in 2016. In addition, I still use DVDs, VHS tapes, and (to a lesser extent) good old-fashioned Torrents for my films and TV shows.
If the internet becomes altogether too bad, there's always Gemini. Making web apps is trickier, but entirely feasible.

I think there was also a federated social media site on Gemini, which could interact with Mastodon, but I can't find it.
Kiwix is a pretty good tool. The only real disadvantage (as far as I know) is that edits to the pages often take a long time to come through after they're made on Wikipedia (or whichever wiki you're looking at); sometimes weeks or months.
