I think it's clear there is a relationship between the two. Perhaps incidental, but they're still bound together. According to the article, the only implementation on the US side was by presidential policy directive. So our faith in the US implementation of the 'privacy shield' is only as good as our faith in the integrity of said Directive. Even starting from a low point where it's quite clear Trump is interested in tearing up anything Obama put his name to; his increasingly reckless approach to international relations lowers our faith in any presidential directive by the day. At this point 'privacy shield' either needs to make it into law proper, or we should just assume its days are numbered.
