Will GDPR save us from the products on this list?
GDPR would be a nice "tool" to validate the actual deletion of personal data.
Another example of this is sales tax in the US. Several states have laws that tell the seller to collect and remit sales tax on any sales to residents within the state. But for sellers that have no physical presence in that state, the state has no ability to force them to actually do so (or to force them to open up their books and prove one way or the other).
