I would argue that the Americans getting better privacy protections and working with other countries instead of forcing American companies to behave illegally abroad would be a much better solution than the Europeans watering down their privacy laws.
American companies will set up independent shell companies or subsidiaries to serve European customers anyway. Microsoft and Amazon are never going to voluntary leave a market of 400M customers. Doing so would leave too much room for a competitor to grow and then threaten them. So if fragmenting the web means that Europeans get the same services as Americans, but with better privacy, then I am all for it.
Europeans are to blame for the flaws in the GDPR, not for doing their thing without the blessing of the Americans.
The logic is understandable. Surely, if you just get rid of the abusive American monopolies the home-grown companies will take their rightful places... right?
The only reason the privacy shield agreement was thrown out was due to lack of safe guards from US intelligence.
Even without the privacy shield, US companies would still be able to store EU data in a country with an adequacy decision if it wasn't for the CLOUD act. This seems more to do with US law wanting access to EU data.
The US does not have to give anything in return to get all the private data from EU they want.
The EU in return gets...nothing.
If you are a politician this is not a great position, you get no money, no jobs and no data.
If they equalize data access, "data sharing" (on an intelligence and on a commerical level) could be a valuable component of future negotiations.
The EU gets the services they use....
However from a political standpoint that's as good as nothing.
Could this not also be said about US regulations such as CLOUD act, Section 702 of the Foreign Intelligence Surveillance Act and Executive Order 12333.
I don't think it's accurate to solely blame the EU when this is in response to legislation that gives/gave the US access to all types of personal data on European citizens.
