Can I move my data to the EU before Google shifts it to the US?

Post-Brexit, Sean wants to keep his data protected by the EU's GDPR rather than laxer US privacy laws

Given Google's recent announcement about moving UK users' data to US jurisdiction, what's the best way to migrate to EU-based services? Can you download+upload or crossload your Gmail to another service? And are we in for the same treatment by Facebook, Twitter, WhatsApp, Instagram et al? Sean

Last week Google notified users that "because the UK is leaving the EU, we've updated our terms so that a United States-based company, Google LLC, is now your service provider instead of Google Ireland Limited. We've also changed our privacy policy to make Google LLC the data controller responsible for your information and for complying with applicable privacy laws."
