I think most countries spy on their citizens and a lot of the same countries probably don't want other countries doing the same due to possible unwanted intel leaks in government and corporate sectors.
Not saying it is okay. Pointing out that even if hypocritical there's generally a strategic reason for countries to deter international spying. Would be quite a puzzling decision for any country to provide an open door for other countries to spy on them.
On the other hand if the number keeps going down it helps strengthen hope that it can go down to 0. When these things happen some apparatus gets left behind on how to do it a again for rogue actors inside the country too.
