For anyone trying to be privacy conscious, by deleting their FB accounts, not using all the Google services etc. It should be obvious that a good rule of thumb would also be to not use software built in China.

Even if they were not built with malicious purpose, they have both excellent state-funded hackers and poor security practices in most of their consumer products.

Unfortunately, from what I've seen, I think the same can be said about software from Korea/Japan...
