Oh I agree with that. EC's behaviour in that case is appalling.

There is a way to be safe with regards to EU law, and it's to engineer systems where European data stays in Europe. Of course, the issue is that corporations would then be liable under US' FISA 702.
That's the big issue: the United States made a law that basically states that no US company should follow EU law, and the US admin manages to beat EC officials into submission every few years with another flawed agreement to keep the ball rolling.
