Ok, what if a EU resident goes on a holiday in the US? Will all their data now be open to malicious treatment for the duration of the trip? Or only the data they enter/view during the trip?
This is a good answer. The question has been raised and answered (by tzs and others) on HN so often recently. It‘s interesting to watch how the answers get streamlined to the essential information over time.
That psuedocode is inaccurate - if a company (including its parent's subsidiaries) is not in the EU and does not provide services to companies which operate in the EU, then the GDPR has no inherent jurisdiction.
From my understanding it is correct. It applies to companies outside the EU if they collect data about people inside the EU. If this is enforceable is another question.
> This Regulation applies to the processing of personal data of data subjects who are in the Union by a controller or processor not established in the Union, where the processing activities are related to:
the offering of goods or services, irrespective of whether a payment of the data subject is required, to such data subjects in the Union; or
the monitoring of their behaviour as far as their behaviour takes place within the Union.
I think this is a bit of an oversimplification. How do Facebook's EU subsidiaries fit into this? Can Facebook US simply divest themselves of responsibility in this case?
“offering of goods or services, irrespective of whether a payment of the data subject is required, to such data subjects in the Union; or
the monitoring of their behaviour as far as their behaviour takes place within the Union.”
So Facebook US cannot divest itself as long as it serves customers in the EU or exchanges data about data subjects in the EU with its EU subsidiary.

Edit: slightly less rough, but still quite rough:
