As one other HNer previously mentioned, the cheapest way to stay compliant with GDPR is to completely block access to EU customers. In fact, this is what I did with my business. I redirect to a generic text file (not even a HTML that could trigger a GDPR clause by itself) explaining my stance.
Don't worry about false equivalence that many will raise "So, you don't care about our data HUH?". The intentions behind GDPR may be good. But, the roadmap seems completely stupid. Many think blocking EU customers is an arrogant move. No, it's not. Not everyone has the finance and time to comply with GDPR. A typical re-implementation of our web application will cost us weeks if not months, for example. That could be time spent building features customers want, not fighting some vague elitist law (comply with us or else you're doomed!). If enough business owners block access to EU customers, then, EU will lose a lot of business and that will trigger them to hopefully do something about the vagueness of GDPR. I don't even live in EU, for instance, yet this re-implementation will cost me tens of thousands of dollars (translating my time) that the EU isn't going to pay me for their vagueness.
I've had enough of GDPR. I know many EU HNers will not agree, but please consider putting yourself in a solo founder's shoes.
