I'm not even sure that is true now, but if everyone currently running XP in China moves over to Ubuntu, that's guaranteed to not to be true very, very quickly.

I'm not, and I use Ubuntu. I'd love a good tutorial to start learning about it.

You really don't need to boycott Firefox like the other commenter suggested. Just disable java and set plugins to click_to_play in about:config.

1) Don’t install anything other than via official channels/Ubuntu store or whatever else you trust, like Steam. More importantly, don’t add random PPAs from some guy on the Internet.

2) Boycott Firefox until they get their sandboxing act together. Use Chromium/Webkit2 browsers. Disable Java applets/WS.

Alternatively, go full Stallman[1].
