I'd disagree that nothing has changed. Consciousness of the fact that mass surveillance is happening is much more widespread, and gets brought up in passing from time to time. People have changed their behaviour somewhat - eg many now try to use encrypted communications quite consciously and even Signal has become quite popular for example. It's influence thinking over e.g. use of facial recognition cameras in public places which is unpopular.

And whilst what eg GCHQ actually do hasn't really changed much as far as I can tell, it's been brought onto an "open" legal footing which is progress. The next step will be for the legal safeguards which are currently rather toothless to evolve to have real teeth. I think that will happen eventually but it'll be a slow journey to get there.

It's amazing how people still believe government laws will protect them from spy agencies.

The CIA spied on the Senate and nothing happened.

Much much more websites are HTTPS now. LetsEncrypt was set up, and browsers are better at HTTPS. That benefits people in the UK. "Encrypt everything" was a result of knowing the NSA were hooving everything up.

In the EU, the revelations from Snowdon were successfully used in the data protection cases which overturned the Safe Harbour exemption.
