Data on intra-european transactions and matters is often deliberately shared with the US for intelligence purposes OR is processed by companies in the US, which automatically means that it is used by the US for intelligence.

So, if I use Gmail as a non US citizen, I have to assume that the US government will read/analyze my emails. That's a well recognized fact that I've also been told by people working with classified (German) government data on multiple occasions.
