Well I also assume that many other signals intelligence agencies are collecting data. Having worked at a time for a large global PR firm, I am sure many if not most of our communications were intercepted, especially with work once done for a Chinese based phone hardware maker. I think it would be a massive mistake to assume this is a United States only issue, so far the United States is the only country to have someone leak the information.

So - yes, my most immediate legal concern is how the US government could use the data collection against me contrary to protections given. That doesn't mean there are many more and larger concerns to be thought through, I was merely speaking to one of them.
