Limited and skewed perspectives expressed
Two pertinent perspectives missing from many of the comments to this article are:
(a) most assume that possible decision ramifications in this case will be restricted to Europe "only", and
(b) that European and other International jurisdictions are "easy pushovers" for complying with US Government "strong Arm" political/diplomatic tactics.
There is good evidence from the reactions of many very large International organizations and companies, as well as governments that there is likely to be a great shift"away from" use of "US" owned and/or controlled Data Centers and ISPs, even in foreign locations.
If the US Congress revises Trade/Communications and International treaty laws (unilaterally) to allow demand of data from any entity in USA that communicates overseas, then everyone in the world must wait to see what such imperialistic moves might produce.
Most Americans unfortunately have a very limited worthwhile experience or good understanding of the "realities" that exist in 2014 - 2015 regarding their own country's practical and true (fact based) relationship to the rest of the globe, and make assumptions and decisions - many times erroneous - based solely on US media reports and 'bravado' rhetoric of their politicians/diplomats and talking heads as reported by said US media.
Reality could not be more different.
