I guess Linux is then your only option, and a really old phone as the mobile device. You cannot switch from Windows to Mac (Apple ID) or Chromebook (Google Account), smartphones are out of the question, too, for Android you would need a Google account, for iPhone the Apple ID and for Windows Phone the MS Account.
Also tablets are out of the question. Luckily Linux comes to rescue for you. It's good to have principles, however...
