But, although China could monitor me, why would they care about some random guy out of 300 million Americans? And even if they cared, what could they do that might actually affect my life?
In contrast, we know that many US companies have an open wire to American law enforcement and surveillance agencies. And these people do have an interest in monitoring me (even if I'm not doing anything wrong), and they do have the power to harm me.
China might be eviller in many respects, but the products of a Chinese company are harmless to me, especially in comparison to domestic ones.
(And I also use Kaspersky for security on my home computers.)
In some ways it's worse because Australia is five-eyes, so they can do a, I'll spy on your citizens you spy on mine kind of thing (which we know from Snowden was exactly what they were doing)[1][2].

No, thanks. Google may be evil but moving my data from Google to the Russian government spooks is really not a solution.
