> According to some privacy experts, even a third party just having a US-based supplier might be construed as a customer of that third party being in violation of GDPR, at which point we'd basically have to cease all economic activity.
That's the only thing I was really replying to here at the start.
As of now, as a business you essentially have three alternatives:
1. Run the entire infrastructure you need yourself or have it run by EU-based companies guaranteed to have no relations with US-based entities whatsoever (Good luck with finding those ...). This, for example, includes payment systems and banking infrastructure, because guess where many EU-based banks host their infrastructure? That's right, AWS.
2. Go out of business.
3. Ignore this aspect of GDPR for now, document everything, continue to do your own due diligence, and hope for the best.
Those abusing personal information without consent deserve all the fines that can be thrown at them. I'd rather there were personal liability in the same manner as Title IX of Sarbanes-Oxley, but in the meantime, this is the best there is.
