As a non-US person I'm not concerned about the NSA, it doesn't have a material impact on me, it's not like the NSA orders a black helicopter to snatch me from Germany. I'm worried about corporate use of my data because that stuff can actually realistically leak or be used for ads or whatever else and in this case I have probably better default protections with a Swiss company than with a US based one. (with some exceptions of course, Signal and so on seem trustworthy).
