Now, please tell me that American companies are better at privacy than the Chinese ones.
Btw, some alternative email providers in truly democratic countries:
* ProtonMail (Switzerland)
* TutaMail, Posteo, Mailbox.org and Eclipso (Germany)
* Runbox (Norway)
* Mailfence (Belgium)
If you have sensitive things in your emails, host your own mail, use GPG encryption or a one-time pad, or even avoid electronic networked machines altogether (depending on the level of security that you require).
Switzerland-hosted services are no safer than others, recall that Crypto AG, who promised to sell secure encryption machines, were just a cover by foreign intelligence services (jointly US/DE-owned/operated by the CIA & BND).
This is such a myopic view of the situation. Are you going to only exchange emails with people you host as well? Otherwise, anyone you exchange emails with will go through other email providers.
Chinese companies give data to China.
I don't trust either of them, but if I had to choose, I would use Chinese products in the U.S. and vice versa.
Say what you want about especially Germany, but there you don't get sued by the president for billions if he doesn't like your opinion.
