Diversity is actually really valuable for everyone. For everyone that is not of geopolitical interest and a potential target of espionage (e.g. politicians, military, executives at multinationals), the best approach to protecting privacy is to adopt technologies from jurisdictions outside your own. A citizen or resident of of the US most likely has to worry more about his own government adopting the policies of "Lavrentiy Beria" than China. The same goes for Chinese citizens and residents adopting US technology to protect them from their government.
A US citizen worried about his privacy being used against him could use Yandex for email and a Russian citizen worried about his privacy could use GMail.
As a Canadian, you're probably more protected using Chinese technologies and services, since you're more likely to cross over into the US and because Canada is part of the Five Eyes.
