For one thing, I think classical spying between governments is just good thing. Knowing what other sovereign actors do and think without filters removes suspicion. Government officials getting spied on just shows incompetence from those go spied and they should up their game. I think security agencies in many countries will now update their policies and get funding for doing so.

Also. Mass surveillance of citizens is very different from targeted surveillance of small number of suspects. Mass surveillance changes the power balance in democracy. Targeted surveillance of select number of people fits into normal intelligence work.
