I also use Linux & Ungoogled Android on everything–and it is the best we got now that doesn’t involve a significant time sink or expertise to get things working. I would love to see alternative platforms be popular & with general hardware compatibility & either Nix or Guix support as well, I would consider giving it a run in the future since I like being open if something better is on offer. I like to keep light tabs on the Haikus, BSDs, OpenIndianas, & such of the world just in case… particularly if we ever got a memory-safe kernel with some proofs behind its logic (Rust doesn’t go hard enough, sorry fanboys). That said, generally, Linux is still good.
