@Walter Hinteler,
Encrypted anything you put on the internet that you would not wish to be on the front page of the New York Times and it is not an issue.
The most important issue is that the US government is doing it very best to made damn sure no one will trust any US firm with their private information.
Just as a matter of best practice do not used an American firm for your email, your cloud storage or your VPN provider and of course that suggestion go to Americans as well as the rest of the world.
footnote that also go for the UK base firms and the other five nations that is in bed with the NSA.
