Your comment led me to wonder if any businesses are considering raising prices for EU customers as a result of this law. I'm not so much wondering about the "we lost revenue because we can't sell your data anymore", but more along the lines of "complying with the regulatory environment in this region is expensive, and we pass the cost of compliance along to customers in the region".

I recently learned about the AU warranty rules, which are very consumer-friendly — and which a commenter pointed out might be the reason that Apple and others charge significantly more when selling products in AU.

Note: I'm not saying anyone should raise prices as a result of GDPR, just wondering if anyone has done so.
