How about cost of compliance? For example, just the fact that you need to figure out whether you are compliant or not costs money. If you ask for user consent, then you must be able to later show that you got said consent from the user to work that data. You also have to take into account the risk of fines if something somewhere goes wrong. We, as software developers, should be intimately aware of how things can go wrong despite everyone trying their best.
All of these things cost money. If the cost is greater than what the business from the EU brings in, then it's not worth it. The fact that there are people who immediately and only jump to the thought they don't care about privacy is very worrying.
