Fedora and fallback DNS servers

You should realize that using Tor has ramifications that may be even worse than the privacy concerns regarding Google or Cloudflare. There are places in the world where using Tor may draw suspicion towards an otherwise ordinary user, resulting in consequences far worse (such as an arrest) than a few logs in a megacorp's database. And I'm not talking about people who are at odds with the powers that be; this is about the Plain Joes (like, say your parents): they lead an ordinary life, and you set up a Linux system for them because they just want to browse the internet, and Fedora works pretty well for them, while not making proprietary OS makers even richer. You live far away, so if their ISP-supplied DNS fails for a day, there's still a fair chance that the fallback DNS works and they won't notice anything. When the ISP fixes the problem, you'll be back to using their DNS instead of Google or Cloudflare.
