Why haven‘t all those doomsayers closed down their businesses long before the GDPR?
There are varying degrees to which people see laws as affecting them. Small business tech owners, when a law says they have work to do, are going to feel affected. If there was a securities or accounting law that felt similarly overreaching one could expect a similar reaction. This is especially true if there is an alternative (locking out markets) that is easier. It's not helpful to try and compare the situations. It's also not fair to consider people weighing the costs of these laws as doomsayers. They aren't closing down their business, they're just restricting it to more business-friendly environments in their view.
People in other parts of the world have gotten used to that. As a current example, see US threats re: European business with Iran.
Even if the GDPR were overreaching (and I vigorously dispute that notion), it would simply be a taste of America‘s own medicine.
I was just pointing out, that when a lawyer says "probably", he usually has a good reason to do so. And it's my strong belief that the reference cases in court will not be fought by small companies, because they rarely are.. There is just not enough money to make fit the effort you need to put in winning the first case. Before there is not one single case, I don't think it's necessary to panic and shut everyone out.
You don't need to believe me or agree with me, but reducing this to "my personal appetite for risk" is really weird.
Maybe you have huge assumptions that people reading what you say will add all kinds of limitations to what you say? I don't. It leads to terrible discussions, like this one.
Regarding the personal risk comment, I could've been more clear: From what I got, no lawyer can give you a guarantee at the moment, that what he says is actually what will happen. So in the end you'll have to take action based on recommendations, and take a risk - or, as the op, shut out all European users completely. My personal risk is continuing to do business in the EU, even with this uncertainty. You couldn't have guessed all that from my earlier comment, so I agree it was bad..
I'll try to do better.
