You’d be shocked at the number of people in regulated industries that thinks a VPN inherently makes them more secure. If you think your traffic exits in the US and it exits in Canada — or really anywhere that isn’t the US — that can cause problems with compliance, and possibly data domicile promises made to clients and regulators.
At minimum, not being able to rely on the provider that you are routing your client’s data through is a big deal.
