European companies operate under stricter privacy laws. GDPR is applicable world wide but has serious teeth and enforcement within Europe. Small US companies with no presence in Europe can effectively ignore it. However if an American were to choose a European service this benefit is effectively passed on to them. They can view what data any company has on them or ask them to delete it.

I can appreciate some don't care about their data especially in this world of people pouring their lives in to social media but some people do care.
