Idk (I’m not op) but I think when people say “can I install Linux on this” everyone knows they mean gnu/Linux. Yes, if I’m picking a container base image obviously alpine is also Linux, and if we’re talking about kernels then Android is too. But if we’re talking about desktop OSes then I think it’s close enough.
Putin maybe, Kim-Jong definitely not. Just Meta’s net profit (let well alone revenue) is well over NK’s entire GDP. Even if he literally owned the entire country which he certainly does not, he wouldn’t be nearly as wealthy as Musk or Bezos.
